Southern Short-tailed Shrew
The southern short-tailed shrew (''Blarina carolinensis'') is a gray, short-tailed shrew that inhabits the eastern United States. Description The southern short-tailed shrew is the smallest shrew in its genus, measuring in total length, and weighing less than . It has a comparatively heavy body, with short limbs and a thick neck, a long, pointed snout and ears that are nearly concealed by its soft, dense fur. As its name indicates, the hairy tail is relatively short, measuring . The feet are adapted for digging, with five toes ending in sharp, curved claws. The fur is slate gray, being paler on the underparts. Distribution and habitat The southern short-tailed shrew is found in the southeastern United States, from southern Virginia to eastern Texas, to central Oklahoma, and in the Mississippi valley as far as southern Illinois. Within this region, it is found primarily in pine forests. However, these range from dry to wet and even swampy habitats, as well as disturbed forests a ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Short-tailed Shrew
The northern short-tailed shrew (''Blarina brevicauda'') is the largest shrew in the genus ''Blarina'', and occurs in the northeastern region of North America. It is a semifossorial, highly active, and voracious insectivore and is present in a variety of habitats like broadleaved and pine forests among shrubs and hedges as well as grassy river banks. It is notable in that it is one of the few venomous mammals. The specific epithet, ''brevicauda'', is a combination of the Latin ''brevis'' and ''cauda'', meaning "short tail". Taxonomy ''B. brevicauda'' is a red-toothed shrew, one of three or four species (depending on the authority) in the genus ''Blarina''. It was formerly considered to be a sister subspecies of the southern short-tailed shrew (''B. carolinensis''). The species has been divided into 11 subspecies based on morphological characteristics, which are grouped into two semispecies: ''B. b. brevicauda'' and ''B. b. talpoides''; these groupings were mirrored by a molec ...

Elliot's Short-tailed Shrew
Elliot's short-tailed shrew (''Blarina hylophaga'') is a small, slate grey, short-tailed species of shrew. Its common name comes from Daniel Giraud Elliot, who first described the species in 1899. Description Elliot's short-tailed shrew is similar in appearance to the closely related southern short-tailed shrew, although slightly larger on average, and was long thought to belong to the same species. It is a heavily built shrew with short legs and tail, and a long, pointed snout with long whiskers. The ears and eyes are both small, the eyelids being permanently closed in some individuals, a feature otherwise unknown among shrews. The fur is velvety in texture, and uniformly colored greyish to brown. Adults range from in total length, including the tail, and weigh . Distribution and habitat Elliot's short-tailed shrew is found in lowland environments with heavy vegetation from southern Iowa and Nebraska in the north to parts of Texas and northern Louisiana in the south, includin ...

Shrew (animal)
Shrews (family Soricidae) are small mole-like mammals classified in the order Eulipotyphla. True shrews are not to be confused with treeshrews, otter shrews, elephant shrews, West Indies shrews, or marsupial shrews, which belong to different families or orders. Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are. It is, in fact, a much closer relative of hedgehogs and moles; shrews are related to rodents only in that both belong to the Boreoeutheria magnorder. Shrews have sharp, spike-like teeth, whereas rodents have gnawing front incisor teeth. Shrews are distributed almost worldwide; among the major tropical and temperate land masses, only New Guinea, Australia, and New Zealand have no native shrews; in South America shrews appeared only relatively recently, as a result of the Great American Interchange, and are present only in the northern Andes. The shrew family has 385 known species, making it the fourth-most sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-toothed Shrew
The red-toothed shrews of the subfamily Soricinae are one of three living subfamilies of shrews, along with Crocidurinae (white-toothed shrews) and Myosoricinae (African white-toothed shrews). In addition, the family contains the extinct subfamilies Limnoecinae, Crocidosoricinae, Allosoricinae and Heterosoricinae. These species are typically found in North America, northern South America, Europe and northern Asia. The enamel of the tips of their teeth is reddish due to iron pigment. The iron deposits serve to harden the enamel and are concentrated in those parts of the teeth most subject to wear. The list of species is: * Tribe Anourosoricini ** Genus '' Anourosorex'' (Asian mole shrews) *** Assam mole shrew, ''A. assamensis'' *** Giant mole shrew, ''A. schmidi'' *** Chinese mole shrew, ''A. squamipes'' *** Taiwanese mole shrew, ''A. yamashinai'' * Tribe Blarinellini ** Genus ''Blarinella'' (Asiatic short-tailed shrews) *** Indochinese short-tailed shrew, ''B. griselda'' * ...

Venomous Mammals
Venomous mammals are animals of the class Mammalia that produce venom, which they use to kill or disable prey, to defend themselves from predators or conspecifics or in agonistic encounters. Mammalian venoms form a heterogeneous group with different compositions and modes of action, from three orders of mammals: Eulipotyphla, Monotremata, and Chiroptera. It has been proposed that some members of a fourth order, Primates, are venomous. To explain the rarity of venom delivery in Mammalia, Mark Dufton of the University of Strathclyde has suggested that modern mammalian predators do not need venom because they are able to kill quickly with their teeth or claws, whereas venom, no matter how sophisticated, requires time to disable prey. In spite of the rarity of venom among extant mammals, venom may be an ancestral feature among mammals, as venomous spurs akin to those of the modern platypus are found in most non-therian Mammaliaformes groups.Jørn H.

Lyme Disease
Lyme disease, also known as Lyme borreliosis, is a vector-borne disease caused by the ''Borrelia'' bacterium, which is spread by ticks in the genus ''Ixodes''. The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. The rash is typically neither itchy nor painful. Approximately 70–80% of infected people develop a rash. Early diagnosis can be difficult. Other early symptoms may include fever, headaches and tiredness. If untreated, symptoms may include loss of the ability to move one or both sides of the face, joint pains, severe headaches with neck stiffness or heart palpitations. Months to years later repeated episodes of joint pain and swelling may occur. Occasionally shooting pains or tingling in the arms and legs may develop. Despite appropriate treatment about 10 to 20% of those affected develop joint pains, memory problems and tiredness for at least six months. Lym ...

Babesiosis
Babesiosis or piroplasmosis is a malaria-like parasitic disease caused by infection with a eukaryotic parasite in the order Piroplasmida, typically a ''Babesia'' or ''Theileria'', in the phylum Apicomplexa. Human babesiosis transmission via tick bite is most common in the Northeastern and Midwestern United States and parts of Europe, and sporadic throughout the rest of the world. It occurs in warm weather. People can get infected with ''Babesia'' parasites by the bite of an infected tick, by getting a blood transfusion from an infected donor of blood products, or by congenital transmission (an infected mother to her baby). Ticks transmit the human strain of babesiosis, so it often presents with other tick-borne illnesses such as Lyme disease. After trypanosomes, ''Babesia'' is thought to be the second-most common blood parasite of mammals. They can have major adverse effects on the health of domestic animals in areas without severe winters. In cattle the disease is known as T ...
