South Georgia, Highlights: [11], Leopard seals are pagophilic ("ice-loving") seals, which primarily inhabit the Antarctic pack ice between 50˚S and 80˚S. In response to a petition received by the American US Fish and Wildlife Service (FWS), suggesting that the Service should reclassify the leopard’s status throughout its range, from ‘threatened’ to ‘endangered’, in terms of the American Endangered Species Act (ESA), on 20 December 2017 the Service issued a document (ID: FWS-HQ-WS-2016-0131-0742) entitled “Endangered and Threatened … [22] The leopard seals have age-related differences in their calling patterns, just like birds. The leopard Seal is endangered MAINLY because either the whales are eating them and also Humans are leaving rubbish in the sea where they swim. As we will demonstrate with these 10 leopard seal facts, however, this amazing Antarctic animal is well worth a closer look. Pups are born on ice floes and kept in small snow holes that the female leopard seals dig out during their pregnancy. This is possible by increasing surfactant which coats the alveoli in the lungs for re-inflation. [47], From a conservation standpoint, the only known predators of the leopard seals are killer whales and sharks. [31], The only natural predators of leopard seals are the killer whale and possibly the elephant seal. The trait of vocalizing underwater for long periods means they can be the subject of acoustic surveys, allowing researchers to gather most of what is known about them.[20]. This cruise delivers you to wondrous landscapes found in one of the harshest environments on Earth. Although theyare not endangered speciesand their hunting is limited, this is not to say that these measures don´t generate economic benefits to the inhabitants of the localities near the waters where they live. Is the leopard seal endangered? But because leopard seals breed in water, scientists have hypothesized that their acoustic communications play an important role in locating and selecting a mate. His experience, he later said, was one he will never forget. [21] While singing the seal hangs upside down and rocks from side to side under the water. [28] Leopard seal pups mortality rate within the first year is close to 25%. [42][46], Paul Nicklen, a National Geographic magazine photographer, captured pictures of a leopard seal bringing live, injured, and then dead penguins to him, possibly in an attempt to teach the photographer how to hunt. They are also threatened by overfishing, which could potentially collapse the food chain. Its only natural predator is the killer whale. Even so, it can be difficult for scientists to determine what exactly the seals are doing when they produce these vocalizations. Antarctic krill (Euphausia superba), southern elephant seal (Mirounga leonina) pups and seabirds other than penguins have also been taken as prey. Retrieved 2018-05-15. Antarctic krill comprise about 45% of the leopard seal’s diet. Falkland Islands, Ross Sea, All seals and sea lions are protected under the Marine Mammal Protection Act, and some are also listed under the Endangered Species Act. The male leopard seal does not participate in taking care of the pup, and goes back to its solitary lifestyle after the breeding season. It can be a dangerous endeavor to study leopard seals, and in one case, they have been known to kill humans. The females are larger than the males, but the male individuals still quite large compared to other types of seals. [23] However, scientists have identified five distinctive sounds that male leopard seals make, which include: the high double trill, medium single trill, low descending trill, low double trill, and a hoot with a single low trill. Professor Boyd said that Leopard Seal attacks on humans were extremely rare but warned that they may potentially become more common due to increased human presence in Antarctica. Leopard Seals are known to attack the black rubber pontoons of inflatable boats, forcing the boat owners to reinforce the rubber with protective plating, or vacate the premises to avoid damage. They use their front flippers similarly to sea lions (otariids)[36] and leopard seal females are larger than males. A sexually active female (ages 3–7) can give birth to a single pup during the summer on the floating ice floes of the Antarctic pack ice, with a sexually active male (ages 6–7). Lacking the teeth necessary to slice its prey into manageable pieces, it flails its prey from side to side tearing and ripping it into smaller pieces. Their vocalizations consist of “local calls” and long-distance “broadcast calls.” Since leopard seal population densities are low due to their solitary lifestyles, finding a mate can be difficult. The leopard seal also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal).. It also has the distinction of being the rarest seal in American waters. [42] Notable incidents include: In a report read at the inquiry into Brown's death, Professor Ian Boyd from St. Andrews University stated that the seal may have mistaken her for a fur seal or may have been frightened by her presence and attacked in defense. [4] It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, birds and fish. because people throw rubbish in the sea which pollutes the leopard seals While they’re not the longest-living mammal in the world, leopard seals can live for an impressively long … Is possible by increasing surfactant which coats the alveoli in the wild, seals...
