Lynx also inhabit scrub land and tundra in northern regions. In appearance the jaguar is often confused with the leopard. The jaguar can be distinguished by the presence of small dots or irregular shapes within the larger rosette markings, a more stocky and muscular body, and a shorter tail. Seals are able to hold their breath for a long time during dives, using oxygen stored in the blood and muscles as well as the lungs. Seals have large eyes which gives them keen vision both above and below the water.
Seals have a well developed sense of hearing and sensitive whiskers.
Seals have a thick blubber layer which combined with a thick fur coat protects them from the frigid climates in which they live. The lynx is very distinctive, with triangular shaped, tufted ears, a thick set body, long hind legs, a short, stumpy tail and large fur covered paws which help the lynx over deep snow. Only polar bears, brown bears, American black bears and Asiatic black bears hibernate. Other bear species can find food all year round because it is warm where they live. Only brown bears, polar bears and American black bears live in the U.S. and Canada.
