North American beaver large, webbed hind feet. The unwebbed front paws are smaller, with claws. The eyes are covered by a nictitating membrane which allows the beaver to see under water. The nostrils and ears are sealed while submerged. A thick layer of fat under its skin insulates the beaver from its coldwater environment. The beaver's fur consists of long, coarse outer hairs and short, fine inner hairs (see Double coat). The fur has a range of colors, but usually is dark brown. Scent glands near the genitals secrete an oily substance known as castoreum, which the beaver uses to waterproof its fur.
Oily Hare Oily Hare Oily Hare is a Warner Bros. "Merrie Melodies" short, released in 1952, directed by Robert McKimson, written by Tedd Pierce, and starring Bugs Bunny. The title is a pun on oily hair, as with the earlier cartoon "Slick Hare", along with the plot-line actually having to do with oil. The plot is similar to the short "The Fair-Haired Hare", which was released one year earlier and features Orville (Yosemite Sam's brother) as Bugs' antagonist. "Oily Hare" also recycles the same ending where Bugs' home is filled with explosives and blown up. Along Highway $101.00, approximately 531 miles from
