Leopard Seal
One of Antarctica's most voracious hunters
What you need to know about the Leopard Seal
Our Expert Says… "These magnificent predators do have quite gruesome hunting habits. They have a tendency to "play" with the prey, letting it go injured and catching it again, inflicting more damage but releasing. It's almost as if they relish the hunt more than the meal. When they do finally decide it's time to eat they can almost turn prey inside out, such is the ferocity of their jaws. A fascinating and terrible spectacle!"
The leopard seal has a rightfully fierce reputation! This is the second-largest Antarctic seal and the most renowned underwater hunter in the polar region.
With a muscular 3.3m (11ft) long body weighing up to 590kg (1,300lb) and massive, oversize jaws with inch-long canine teeth, the leopard seal is a top predator. They are seemingly fearless and will attack a wide range of prey including squid, fish, and krill when young, moving on to penguins and other seals, including fur seal pups around South Georgia island.
Leopard seals are cold-water specialists, and they hunt around the Antarctic pack ice, following its advance and retreat as the seasons change. They can use their specially adapted teeth to strain krill from the water, and this ability is thought to explain their success, allowing them to move to new areas in search of larger prey while sustaining themselves with the small crustaceans. Their only predator is the orca or killer whale.
The way that leopard seals hunt penguins is both fascinating and gruesome. The seals stay submerged just beyond the ice floe edge where penguins have to jump in or out of the water. The leopard seal uses its unusually large front flippers to move with speed and great agility and catch the penguins by their feet. Once caught, the seals batter the birds against the water’s surface repeatedly until they are dead. They then rip the carcass apart and swallow it.
Little is known about the complete breeding cycle of the Leopard seal as they breed in very remote locations that make observation difficult. It is known that the leopard seals mate in the water and that females haul up on to the pack ice when they are ready to give birth, digging a shallow circular hole in the ice for the pup.
The leopard seal is an apex predator that is superbly equipped for survival in the constantly changing and challenging Antarctic waters.
