The American, or northern, short-tailed shrew ( Blarina brevicauda ) The woodland vole ( Microtus pinetorum ) The snowshoe hare ( Lepus americanus ), typical of Canada, reaches its southernmost distribution in West Virginia.
However, some mammals' teeth do develop differently than humans'. In mice, WNT signals are required for the initiation of tooth development. [9] [10] Rodents' teeth continually grow, forcing them to wear down their teeth by gnawing on various materials. [11] If rodents are prevented from gnawing, their teeth eventually puncture the roofs of ...
The Allegheny woodrat is a medium-sized rodent almost indistinguishable from the closely related eastern woodrat, although slightly larger on average, and often with longer whiskers. Adults typically range from 31 to 45 cm (12 to 18 in) in total length, including a tail measuring 15 to 21 cm (5.9 to 8.3 in).
During the early half of the 20th century, the West Virginia Department of Resources accidentally hatched a somewhat golden rainbow trout. This excitement in the state hatchery fueled the effort to produce the West Virginia "golden rainbow trout." Some anglers claim the state received a golden trout from the west to help culture this. Just the ...
In mammals with tribosphenic teeth, the protocone slides into the talonid basin on the lower teeth in order to grind and crush food. Often the largest cusp in the upper molar, though some insectivorous mammals reduce it substantially. Paracone: A major cusp outwards from the protocone and in front of the metacone.

Mammals chew their food which requires a set of firmly attached, strong teeth and a "full" tooth row without gaps. The manatees have no incisor or canine teeth, just a set of cheek teeth, which are not clearly differentiated into molars and premolars. These teeth are continuously replaced throughout their life with new teeth growing at the rear ...
The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alternating triangles. These molars are an adaptation to a herbivorous diet in which the major food plants include a large proportion of abrasive materials such as phytoliths; the teeth get worn down by abrasion throughout the adult life of the animal and ...
