Leopards have developed a variety of adaptations that help them live in different types of habitats. [11] Most leopard seal breeding is on pack ice. [11] While solitary animals may appear in areas of lower latitudes, females rarely breed there. This way a leopard seal can slow down its breathing to save oxygen and on many occasions it is easy to confuse a specimen that is simply sleeping with a dead animal. Weddells and other true seals even have extra-big spleens to store red blood cells that are released later during a dive.Back on shore, seals enjoy a dive recovery time that's around twice as long as their actual dive time. Like its feline namesake, the seal is a powerful predator high on the food chain.

The mother protects her pup until it can take care of itself; male seals do not take part in parental care. Leopards are excellent hunters, which helps them capture large prey to eat, like antelopes. Because of their limited subpolar distribution in the Antarctic, they may be at risk as polar ice caps diminish with global warming. Young leopard seals usually eat mostly krill, squid and fish. [35] Antarctic krill (Euphausia superba), southern elephant seal (Mirounga leonina) pups and seabirds other than penguins have also been taken as prey. [27], Research shows that on average, the aerobic dive limit for juvenile seals is around 7 minutes, which means that during the winter months juvenile leopard seals do not eat krill, which is a major part of older seals' diets, since krill is found deeper during this time. Sea Lions have a coat with only one layer. Leopard seals use their powerful jaws and long teeth to kill smaller seals, fish, and squid.
