Leopard seals live in the Antarctic and sub-Antarctic waters of the Ross Sea, Antarctic Peninsula, Weddell Sea, South Georgia, and Falkland Islands. This whole process begins in the Antarctic summer, which takes place between November and January, when the seals leave the water and place on the ice to begin their reproductive process. Scientists take blubber thickness, girth, weight, and length measurements of leopard seals to learn about their average weight, health, and population as a whole. Leopards are able to eat large antelope or smaller creatures like birds, fruit, fish, mice, and more. In this way we collaborate in the reduction of the CO2 released by different factories where in some way these materials are processed or used. Leopard Seals have a special arrangement in their jaws.

Onthis regard, several researchers suggest that to prevent this situation some actions should be taken, such as the creation of aquariums or environments under captive fit, where the leopard seals and other seals species can survive without any inconvenience. Gestation Approximately 11 months; with about 1.6 months delayed implantation; pups are 1.0 to 1.6 m (3 to 5 ft.) in length and weigh 30 to 35 kg (66 to 77 lbs.) They have long bodies (10 to 11.5 feet) and elongated heads. Sea Lions have a coat with only one layer.
