3 cze 2020 · We summarized a priori diet information from scat and video analysis and applied a three-isotope (δ13C, δ15N, δ34S), four-source (fish, fur seal, krill, penguin) Bayesian mixing model to examine temporal variability in both prey sources and leopard seal tissues.
Leopard seals mainly eat smaller seals, fish, squid, krill, penguins, and other birds. Diet Carnivore, Molluscivore, Piscivores
Diet. Leopard seals mostly feed on Antarctic krill. They also actively hunt birds like Emperor penguins and warm-blooded mammals like Wedell, Southern Fur, and Crabeater seals. Behavior. Leopard seals primarily lead a solitary life, gathering only around December and January, the ideal season for them to mate and reproduce.
3 cze 2020 · Leopard seal diets in a rapidly warming polar region vary by year, season, sex, and body size.
Background: Resolving the preferred prey items and dietary proportions of leopard seals is central to understand- ing food-web dynamics in the rapidly-warming Antarctic Peninsula region....
Young leopard seals usually eat mostly krill, squid and fish. Adult seals probably switch from krill to more substantial prey, including king, Adélie, rockhopper, gentoo, emperor and chinstrap penguins, and less frequently, Weddell, crabeater, Ross, and young southern elephant seals. Leopard seals are also known to take fur seal pups. [34]
Leopard seals eat a diverse diet, from tiny krill to large penguins and other seals. These predators have evolved specifically for their environment with powerful jaws and excellent swimming abilities that enable them to hunt efficiently in Antarctica’s cold waters.
