Killer whales eat seals, sea lions, squids, fish, walruses, birds, turtles, otters, and penguins, among many other things. They are one of the top predators in the ocean and can eat pretty much whatever they please. They also sometimes eat the remains of other killer whales, making them somewhat cannibalistic. The amount of each food source they eat varies on their location in the world.
Killer whales are predators and feed mainly on other sea creatures. Their diet can vary by location, but mainly they eat fish, squid, and marine animals such as seals and walruses. They have also been known to eat the remains of other dead killer whales.
They will eat squid, fish and marine mammals. They are the top predator of the ocean and are large and fast enough to catch most prey. Killer whales have been found to eat fish from all regions of the sea, both surface and bottom, seals, otters, whales, other killer whales and walruses. Polar bears, reptiles, penguins, seabirds and sharks have all been found in the stomachs of killer whales. The exact diet varies based on habitat.
In the Antarctic, one type of killer whale eats almost exclusively the small Minke whale. A second type eats mostly seals but also Minke and Humpback whales, while a third mainly eats Antarctic toothfish.
In the North Pacific Ocean, resident killer whales eat mostly fish and the occasional marine mammal, while transient killer whales eat mostly marine mammals and rarely eat fish.
Certain populations of killer whales have shown a high degree of specialization. The populations in the Norwegian and Greenland sea specialize in herring and seal. Observations of the northeast Pacific resident killer whales, 96% percent of their diet was comprised of salmon, with 65% of salmon prey being the large, fatty Chinook. On average, a killer whale eats 500 pounds each day.
Killer whales, or orcas, are actually dolphins and not whales. These large carnivores usually eat seals, sea lions, fish, seabirds, squid, and even whales. They are large, powerful killers and hunt in pods. These groups can include up to 40 orcas in each, and each pod uses different techniques and utilizes the ability their numbers play in catching prey.
