Beaver
Beavers have short legs and a stout body with a small, broad, and blunt
head. Massive chisel-shaped incisor teeth have orange outer enamel
because iron has replaced calcium, and this makes them stronger than
most rodent incisors. Upon submergence, folds of skin (valves) close the
nostrils and the stubby rounded ears, and the eyes are protected by a
membrane that keeps water out (nictitating membrane). The fur-lined lips
close behind the incisors, blocking water from the mouth and lungs and
allowing the animal to cut, peel, and carry branches underwater. Small
front feet with five clawed digits dexterously manipulate food. The hind
feet are quite large, and the five digits are connected by webbing,
which makes them useful as paddles for propulsion underwater.
