Some older accounts report S. etruscus at elevations as high as 4250 meters and as low as 100 meters in Malaysia. Can the functional difference between the EDL and soleus muscles of S. etruscus be attributed to different activities of the glycolytic and the oxidative metabolic pathway? Do you know if they die from the cold, the sudden absence of insects for food or other causes? However, much of the evidence appears anecdotal. Of course, wasting time attacking non-prey items that the whiskers brush against would burn precious energy. 5. November 05, 2004 There is no apparent sexual dimorphism. The small size and difficulty of capturing S. estruscus makes it difficult to study. [9][11] They protect their territories by making chirping noises and signs of aggressiveness. Shrews seem to live fast and die hard. I live about 20 miles south of Dallas. (Davison, 1979; Jurgens, 2002), Etruscan shrews are extremely small and therefore little is known about their predation. Your most highly caffeinated, Type A colleague will appear downright slothful compared to a shrew. The Etruscan shrew (Suncus etruscus; also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew) is the smallest known terrestrial mammal by mass, weighing only about 1.8 g. Theyre in constant motion, rarely stopping to sleep. The Etruscan shrew ( Suncus etruscus) weighs only two grams, or less than the weight of a dime. A terrestrial biome found in temperate latitudes (>23.5 N or S latitude). I decided to make my final paper for the class a detailed comparison of the real shrew with the literary one. (On-line). They sure are hungry little things. Because muscles play a major role in the capture and chewing of food, in convective oxygen transport and in the generation of heat, they must be especially adapted to provide the enormous mass-specific rate of energy consumption of the body. The hiding periods are short, and typically last less than half an hour. The elongated rostrum of the shrew has long whiskers referred to as macrovibrissae (Figure 1A, B); the shrew's mouth . Taxon Information Little is known about the mating system in Etruscan shrews. It must stay in constant motion underwater, or it pops back up to the surface. "Suncus etruscus" (On-line), Animal Diversity Web. This tiny animal is characterized by very rapid movements and fast metabolism, eating about 1.5-2 times its own body weight per day. The Weasel on the Toilet & Other Weird Species Discoveries, Indigenous Lands Are Critical for Mammal Conservation. [5][6] They frequent rocks, boulders, stone walls and ruins, darting quickly in and out between them. 3). [9] The head is relatively large, with a long, mobile proboscis, and the hind limbs are relatively small. [5], The Etruscan shrew favors warm and damp habitats covered with shrubs, which it uses to hide from predators. The Animal Diversity Web team is excited to announce ADW Pocket Guides! It must be noted that the closely related species Suncus varilla appears to be monogamous, and pairs live together throughout the year. Walker's Mammals of the world. The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/s) and a relatively large heart muscle mass, 1.2% of body weight. Suncus etruscus is most likely solitary and territorial, except during the breeding season, as is the closely related Suncus murinus. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); this is cool I wrote an essay on this shrew. They have a high metabolism, which means they have to eat. As we celebrate our centenary, we look back at that first issue and the zoologists publishing their work in the new journal. The unchewed food travels to the first two stomachs, the rumen and the reticulum, where it is stored until later. Shrews feed on insects and they use the sense of touch to detect and hunt prey. Accessed March 01, 2023 at https://animaldiversity.org/accounts/Suncus_etruscus/. with a country-wide population of more than 40 million shrews. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. heart rate of resting animals (ambient temperature 22 degrees C) was 835 . In some cases, other skeletal muscles, such as the diaphragm and gastrocnemius muscle,were also studied. What do we know about this jittery creature? The myoglobin concentration is intermediate: type I and IIA fibres are known to have a myoglobin concentration higher than 150 mol 1-1, and type IIB fibres are free of myoglobin in all mammals studied so far. Delivered weekly. at http://members.vienna.at/shrew/itsesAP95-cover.html. These include Suncus madagascariensis, S. fellowsgordoni, S. hosei, and S. malayanus. Although widespread and not threatened overall, they are generally uncommon and are endangered in some countries. The trailer alone was scary. The Etruscan shrew is the smallest known mammal by mass. If you ever get the chance to see one run past, you may think that it had started its day with 5 cups of coffee! The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew, is the smallest known extant mammal by mass, weighing only about 1.8g (0.063oz) on average. What is the heart rate of an Etruscan shrew? [9] The shrew usually has 30 teeth, but the 4th upper intermediate tooth is very small (rudimentary), and is absent in some individuals. In larger mammals, the soleus and the extensor digitorum longus (EDL) muscles are typical representatives of slow-twitch and fast-twitch muscles, so they were chosen to be functionally and structurally investigated in the shrew. The importance of oxidative metabolism is also underlined by the finding of a very high capillary density of up to 2800 mm-2 in the soleus muscle of the Etruscan shrew(Pietschmann et al., 1982) and a very high volume fraction of mitochondria (0.23 in leg muscles, 0.35 in diaphragm) (Hoppeler et al.,1981). That works out to be about 25 beats a second. Myosin light chain composition (fLC1 and fLC2) of extensor digitorum longus(A) and soleus (B) muscle of Suncus etruscus separated by two-dimensional electrophoresis. Stomach contents from three Etruscan Shrews contained small beetles and spiders. The venom paralyzes the creature, but keeps it very much alive. 2). Clicking sounds are heard when these shrews are moving, which cease when they rest. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Nowak, R. 1990. These shrews prefer warm and damp climates and are widely distributed in the belt between 10 and 30N latitude stretching from Europe and North Africa up to Malaysia. The basal metabolic rate of these tiny creatures averages 3.22 cubic centimeters of oxygen per hour. Significance levels are calculated for the difference between extensor digitorum longus (EDL) and soleus: *P<0.05, **P<0.01 (unpaired t-test). Shrewlets are born naked and blind, weighing only 0.2 g (0.0071 oz). And then theres the literary work, Shakespeares Taming of the Shrew. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. Conservation science in action. There are unconfirmed reports of the Etruscan shrew in West and East Africa (Guinea, Nigeria, Ethiopia) and in Armenia, Brunei, Indonesia, Kuwait and Uzbekistan. As shown in Table 3, the number of type I fibres in soleus muscles decreases and the percentage of fast-twitch fibres increases with decreasing body mass in a range of mammals. Etruscan shrews are also sensitive to weather changes, such as cold winters and dry periods. Type IID fibres combine a high shortening velocity which, according to studies in rats is highest in type IIB fibres, a little lower in type IID fibres and considerably lower in type IIA and I fibres, and a low fibre diameter, which is lowest in type I and IIA fibres, a little larger in type IID fibres and largest in type IIB fibres(Galler et al., 1994). Characteristics of force and Ca2+ transients of fibre bundles of the extensor digitorum longus and the soleus muscles of Suncus etruscus at 25C. Heres a glimpse of what the Etruscan shrew looks like. Even their brain mass dropped by 2030%.. I wish for another politician like him nearly every day. The . In addition,SDSPAGE and two-dimensional electrophoresis of EDL and soleus muscles showed no difference in the pattern of myosin heavy chains and myosin light chains. 1998. (Davison, 1979; Hutterer, et al., 1979; Nowak, 1990), Suncus etruscus is an insectivorous species, as are most other shrews. One study of S. etruscus pairs found that the gestation of this species was about 27.5 days and that litter sizes were anywhere from 2 to 6. (Nowak, 1990), There is little known about the life span of Suncus etruscus, but the lifespans of other species in the genus range from 1.5 to 3 years. Grasshoppers are their favorite. We had the unique opportunity of studying, for the first time, the helminth community of a total of 166 individuals of the Etruscan shrew. They dont use their forefeet to aid in consuming food. The same two types of fast light chains, fLC1 and fLC2, with molecular masses of 24 and 21.5 kDa, were detected in the EDL and soleus muscle(Fig. Live hoarding sounds innocuous enough, but in reality it shares numerous plot points with that terrifying movie Hostel. Storyteller.travel shares the best travel insights, facts, and photos. In order to defend their territories, they all make some sort of chirping noises and show aggressive behavior toward any intruders. Table 1. The ratio of LDH/CS activity, given in Fig. Ferry, A. I am a conservation biologist working on species at risk in southwest BC and we have the endangered Pacific Water Shrew here (Sorex bendirii). Etruscan shrews frequent rocks, boulders, stone walls, and ruins, darting quickly in and out between them. On this Wikipedia the language links are at the top of the page across from the article title. 8. While this varies among species, a shrews heart rate beats 800 to 1000 times per minute. [6] They reach their maximum level of activity at dawn. This is especially true in the case of Suncus etruscus; being such a small animal, it has high energy demands. 1 B and C).We refer to the large whiskers on the side and top of the shrew's rostrum as macrovibrissae ().The longest macrovibrissae had a length of 12 mm, a considerable length similar to that of mouse . The Etruscan shrew, Suncus etruscus, is not only the smallest terrestrial mammal, but also one of the fastest and most tactile hunters described to date. For an animal that has to eat constantly, this keeps a fresh if unsavory meal always at the ready. Theodore Roosevelt (yes, the president) observed a water shrew catching a minnow in North Idaho. They are also found in the Maltese islands, situated in the middle of the Mediterranean Sea. Etruscan shrews are also sensitive to weather changes, such as cold winters and dry periods. Because they have a very high metabolism, Etruscan shrews have a ferocious appetite. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. 10.2305/IUCN.UK.2017-2.RLTS.T90389138A22288134.en, "Rates of rewarming, heart and respiratory rates and their significance for oxygen transport during arousal from torpor in the smallest mammal, the Etruscan shrew, Suncus etruscus. Long ago I worked in an arboretum in upstate New York. One week my job was to clean up a poorly maintained slope covered with various evergreen species. It feeds on various small vertebrates and invertebrates, mostly insects, and can hunt individuals of the same size as itself. This difference was confirmed by force measurements on fibre bundles from these muscles, which were performed together with recordings of the Ca2+ transients(Wetzel and Gros, 1998). The fur becomes denser and thicker from fall through the winter. (Hutterer and Kock, 2002), Shrews are food for predators such as owls, and probably play a large role in controlling insect populations. The solid line is the result of a linear regression on a double-logarithmic scale in which all data points were included: log(LDH/CS)=0.304logMb+0.623; r2=0.62). Shrews emit a sound described as a twitter and it is often assumed this is used in echo-location. ("Eurasian Insectivores and Tree Shrews: Status Survey and Conservation and Action Plan", 1995; Nowak, 1990). Heart rate was obtained from electrocardiograms (ECGs), recorded via foot electrodes. When they are still, they tend to hide under dead leaves, but this has never been seen for more than a half an hour. [3][4][5][6][7] (The bumblebee bat is regarded as the smallest mammal by skull size and body length.[3][8]). The Fura2 technique is described in detail by Wetzel and Gros(1998). The Etruscan shrew (Suncus etruscus) is also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew.It is the smallest known mammal by mass. I loved all of the details you shared about shrews, and particularly your anecdote about the Shakespeare paper! And so at least one shrew species shrinks. The American Chemical Society reports that a mealworm can be kept, paralyzed but alive, for 15 days. In the wild they tend to move based on the availability of cover and leaves to hide under. They have poor eyesight and often live in thick cover filled with obstacles. [3] The fur color on the back and sides is pale brown, but is light gray on the stomach. Fascinating stuff. for N measurements per muscle bundle. 14. Thanks for reading the blog. the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south. Here,both time to peak force and times to 50% and 75% relaxation were significantly shorter in the EDL than in the soleus muscle, and the rise and decay of the cytosolic Ca2+ concentration were significantly faster in EDL muscle (Table 2). Journal of Biogeography, 25: 1105-1113. They protect their territories by making chirping noises and signs of aggressiveness. Instead, shrews rely on their long, highly sensitive whiskers, also known as vibrissae. One ate the other and could not get out. Where in the world do Etruscan shrews live? It is characterized by very rapid movements and a fast metabolism, eating about 1.52 times its own body weight per day. that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle). Mediterranean forests, woodlands, and scrub, https://en.wikipedia.org/wiki/Etruscan_shrew, https://www.iucnredlist.org/species/90389138/22288134. Immunohistochemical studies with monoclonal and polyclonal antibodies are described in detail by Peters et al.(1999). Suncus fellowgordoni is endangered; Suncus hosei is vulnerable. Conservation science, field reporting, and cool creatures. Baby shrews are called cubs. Etruscan shrews probably play an important role in controlling insect populations due to their diet. [6] Near the mouth grow a dense array of short whiskers, which the shrew actively uses to search for prey, especially in the night. When Suncus etruscus is in torpor and then suddenly awakened it makes harsh shrieking calls and this noise is usually only made when it is unable to flee the area. After their eyes open at 14 to 16 days old, they mature quickly. Many sources mention that some shrews use echolocation: they emit sounds producing sonar that helps them navigate their world (much like bats). Yay for Natures students always learning from Her. When the cow first eats, it chews the food just enough to swallow it. Histochemical staining for myosin ATPases revealed identical fibre type patterns in the EDL and soleus muscle. Is the Etruscan shrew the smallest mammal? (Nowak, 1990; Nowak, 1990), Shrews in general are very active and always foraging for food. Im a travel and nature enthusiast. The skeletal muscles of S. etruscus contract at up to 900 min-1 for respiration, up to 780 min-1 for running and up to 3500 min-1 for shivering. Shrews may be fierce predators, but theyre small, which means they in turn become prey. Two-dimensional electrophoresis of myosin light chains was performed using the method of O'Farrell(1975). They are also food for local predators such as birds of prey and especially owls. These values are 25, 67 and 250 times higher than those of humans at rest. and across multiple seasons (or other periods hospitable to reproduction). Electrophoresis of myosin heavy chain isoforms was carried out for 18 h at 4C according to the method of Kubis and Gros(1997) with minor modifications. Etruscan shrews are more active during the night when they make long trips; during the day, they stay near the nest or in a hiding place. The Etruscan shrew is estimated to live up to 2 years. Most adults weigh 1.8-3 g with a body length of 35-48. Suncus varilla young stay with their mother for up to nine months after being weaned, whereas S. murinus young are separated from their parents within a few months. While ancient sources have been interpreted in a variety of ways, the Greeks called always the Etruscans Tyrsenoi, although not all . The mean +/- S.D. It hunts caddis larvae and other small aquatic prey. Clicking sounds are heard when these animals are moving, which cease when they rest. Grasshoppers, where common, are often regular prey. Thank you very much, Michael, and thanks for reading Cool Green Science! At 22C, a rate of 270 ml kg-1min-1 has been recorded (Fons and Sicart, 1976) and a maximal value of 1000 ml kg-1min-1 (Weibel et al.,1971; Jurgens et al.,1996) has been estimated. The paper received an A, along with the pointed suggestion that I pursue a career in nature writing as opposed to academia. No, despite appearances, shrews are not rodents (like mice, rats, hamsters, etc.). Traveling to a country where you dont speak the language? By 3 to 4 weeks of age, the young are independent and are soon reproductively mature. Then it strikes quickly and with great precision. CK activity is functionally coupled to the activity of the Ca2+-ATPase because CK controls the local [ATP]/[ADP] ratio at the sarcoplasmic reticulum and, thus, determines the ATP concentration available for the Ca2+-ATPase and, therefore, the velocity of muscle relaxation(Minajeva et al., 1996). In other words, India and southeast Asia. Bonner Zoologische Beitrage, 50/3: 249-259. As a lifelong mammal nerd, this amounted to heresy. Check out this post about rhino beetles. Measurements of the activities of lactate dehydrogenase (LDH) and citrate synthase (CS) revealed no significant difference in activities between the two muscles(Table 5), suggesting that the functional difference between the EDL and soleus muscles cannot be explained by different activities of CS and LDH. [2] In some regions it is rare, especially in Azerbaijan, Georgia, Jordan and Kazakhstan (included into the Red Book). The Etruscan shrew Suncus etruscus (also known as white-toothed pygmy shrew) is the smallest terrestrial mammal with a body weight of 2 g and a body length of around 4 cm without tail (Figure 1a). We also share travel tips, packing lists, and gear reviews. Etruscan shrews occur from Europe and North Africa up to Malaysia. He described it in his book The Wilderness Hunter: It was less in size than a mouse, and as it paddled rapidly underneath the water its body seemed flattened like a disk, and was spangled by tiny bubbles, like flecks of silver.. Many wildlife species feast and bulk up for the cold winter months. Superficially, many of these species look similar, with most having pointy snouts, a streamlined body and a grayish coloration. The valuable help of his technical assistant,the late Jean-Pierre Clara, is unforgettable. A terrestrial biome. It feeds on various small vertebrates and invertebrates, mostly insects, and can hunt individuals of the same size as itself. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). The common adjective is "nocturnal", A carnivore meaning 'meat eater' is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of a An insectivore is a carnivorous plant or animal that eats insects. Search in feature Anna Ferry (author), University of Alaska Fairbanks, Link E. Olson (editor, instructor), University of Alaska Fairbanks. This constant need for food has led to some truly bizarre and even disturbing adaptations. The results might be explained, at least in part, by an effect of creatine kinase (CK) activity on Ca2+-ATPase activity. Suncus varilla apparently reaches sexual maturity about 24 months after birth. You can spend way too much time on YouTube watching videos of shrews attacking mice, scorpions, snakes and other larger creatures. Davison, G. 1979. Owl pellets often contain the remains of Etruscan shrews. A larger volume fraction of sarcoplasmic reticulum and, hence, greater numbers of Ca2+ channels and higher Ca2+-ATPase activity in the EDL could also be responsible, but these have not been measured. Suncus etruscus may be one of the smallest mammals living today, with most adults weighing between 1.8 and 3 grams and ranging from 35 to 50 mm in length. McNab, B. Moved out here in 1982 & had never seen one of these shrews before. Klaus D. Jurgens; Etruscan shrew muscle: the consequences of being small. This may be partly because smooth movements of a muscle require asynchronous firing of its motor units. etruscan shrews ~ does it have 800 stomachs? Etruscan shrews occur from Europe and North Africa up to Malaysia. 5) and subsequent immunoblotting with anti-CK antibodies, it has been shown that cytosolic CK is present in remarkable amounts in shrew muscles and that its concentration in the EDL muscle is three times higher than in the soleus muscle. Suncus murinus young have been seen caravanning behind their mother when they are learning to find their own food. Gravitational forces, which are proportional to body mass, decrease with decreasing body size, and the locomotory behaviour of the smallest mammals reveals that moving is much more important for them than standing. offspring are produced in more than one group (litters, clutches, etc.) South Coast Conservation Program The Etruscan shrew has a body length of about 4cm (1.6in) excluding the tail. uses smells or other chemicals to communicate. If you havent already? The Etruscan shrew is the smallest mammal in the world by mass. ("Eurasian Insectivores and Tree Shrews: Status Survey and Conservation and Action Plan", 1995), There are no known negative affects of Suncus etruscus on humans. A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. Differences in isometric twitch contraction times between different muscles are, at least in part, probably due to differences in cytosolic creatine kinase activities. They can be found at sea level but are usually confined to the foothills and lower belts of mountain ranges. The Malayan Nature Journal, 32/3 and 4: 227-231. This heavy chain type was identified as the isoform HCIId by comparison with myosin electrophoresis from rabbit muscles (Fig. The Etruscan shrew is an incredible little mammal. Journal of Experimental Biology launched in 1923 as The British Journal of Experimental Biology. Repeat until five were trapped and either eaten or unable to get out because they had eaten. [3] In comparison, the related greater white-toothed shrew can be twice as long and weighs four to five times more. The Etruscan shrew , also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew is the smallest known mammal by mass, weighing only about 1.8 grams on average The bumblebee bat is regarded as the smallest mammal by skull size). The importance of the oxidative metabolic pathway is supported by the capacity of the shrew's type IID fibres to store oxygen bound to myoglobin. Specific activities of lactate dehydrogenase and citrate synthase in the extensor digitorum longus, soleus and gastrocnemius muscles of Suncus etruscus. They are always looking for food in order to meet their high energy demands. Find out more and apply here. They are also found in the Maltese islands, situated in the middle of the Mediterranean Sea. Shrews have been recorded making 12 body movements per second. The Etruscan shrew has a slender (not truncated) body, with a length between 3 and 5.2cm (1.2 and 2.0in) excluding the tail, which adds another 2.4 to 3.2cm (0.94 to 1.26in). (Davison, 1979), Suncus etruscus may be one of the smallest mammals living today, with most adults weighing between 1.8 and 3 grams and ranging from 35 to 50 mm in length. Etruscan shrews are hard to keep alive in captivity due to their size and their large energy requirements. To record the twitch contractions, a force transducer based on a semiconductor sensor device AE 802 (SensoNor a.s.,Horten, Norway) was developed (Peters et al., 1999). The largest living terrestrial animal is the African elephant, Loxodonta africana, with a body weight up to 7.5 tons. Convergent in birds. This is in accordance with the observation that contractions of motor units occurred at a frequency of 58 s-1 during shivering(Kleinebeckel et al., 1994). The Etruscan shrew (Suncus etruscus) is one of the smallest mammals on earth and is used in many fields of research, including physiology, behavioral science and neuroscience.However, establishing and maintaining a breeding colony of this species in the laboratory can be challenging, as it requires specific husbandry conditions that greatly differ from those of more common laboratory species . Pairs usually form in the spring and may tolerate each other and their young for some time at the nest. There isnt evidence that this echolocation is used to find prey. The Etruscan shrew, the smallest terrestrial mammal on earth, has a heart rate that can reach 1500 beats per minute, more than any other mammal and more even than the hummingbird. Etruscan shrews are small mole-like creatures that are one of the most voracious animals known that devour a great deal of food. An article in the journal Biology Letters found shrew-like calls can indeed yield echo scenes useful for habitat assessment at close range.. These small animals favor warm and damp habitats covered with shrubs, which they use to hide from predators. Disclaimer: If mama shrew has to relocate the babies, they will form a train, with each cub biting the tail of the cub in front of them. Vocalization of the Shrews Suncus etruscus and Crocidura russula during Normothmia and Torpor. It weighs only around 1.8 grams (0.063 oz) on average. The Etruscan shrew, also known as the white-toothed pygmy shrew or Suncus etruscus, is located in North America. The Etruscan shrew Suncus etruscus (Savi) and the bumblebee bat(Craseonycteris thonglongyai), both weighing on average less than 2 g, are the smallest extant mammals. If you encounter a swarm, look for shrews scurrying along its tail edge.. It feeds mostly on various invertebrates, including insects, larvae and earthworms, as well as the young of amphibians, lizards and rodents, and can hunt prey of nearly the same body size as itself. Although usually homeothermic, the species undergoes torpor cycles during times of food restriction and at low ambient temperatures. The shrew can then move it to a cache, available for whenever hunting is not going so great. Shrew muscles, in general, seem to be composed of type II fibres only but, within this family,there is a correlation between body mass and HCII-subtype composition(Table 4). "Eurasian Insectivores and Tree Shrews: Status Survey and Conservation and Action Plan" J Exp Biol 1 August 2002; 205 (15): 21612166. The activity of metabolic enzymes leads to the conclusion that aerobic metabolism may meet any level of energy demand by the animal so that glycolytic metabolism is not necessarily required for ATP production. Etruscan shrews also have a mouthful of teeth (usually 30). The shrew's skeletal muscle consists entirely of fast-twitch types and lacks slow fibres. The rate at which Ca2+ is released from the sarcoplasmic reticulum and subsequently resequestered is significantly higher in the EDL than in the soleus muscle of S. etruscus(Table 2). This does not deter other predators, like owls and snakes. Pairs usually form in the spring and may tolerate each other and their young for some time at the nest. A shorter relaxation time could be the result of a higher concentration of parvalbumin in the EDL,but immunohistochemical investigations have provided no evidence for the presence of parvalbumin in shrew muscles(Peters et al., 1999). CK,creatine kinase. By three to four weeks of age, the young are independent and are soon sexually mature. The cow has four stomachs and undergoes a special digestive process to break down the tough and coarse food it eats. Lane M, myosin heavy chains HCI and HCIId of rabbit muscles. The IUCN Red List and other sources dont provide the number of the Etruscan shrew total population size. The water shrew has stiff hairs on its feet that allow it to scamper across the surface of the water. This is because many shrew species are venomous. A lot.
