orca diet

More than one-third of U.S. fish and wildlife species are at risk of extinction in the coming decades. These powerful predators feed primarily on other marine mammals, including seals, sea lions, and even whales. Such extremely different feeding habits, which is not known to occur in any other sympatric mammal species, has also resulted in significant differences in vocalizations, echolocation, group size and behavior between the two ecotypes. In many parts of the world, killer whales prey on fishes or marine mammals, but not both. In the Antarctic, individual killer whales slide out onto ice floes to hunt penguins. Specific populations, like those found in Puget Sound, can develop specialized diets of fatty fish such as salmon or herring. Come with us on an unforgettable journey behind the scenes during a SeaWorld or Busch Gardens Camp.

Female orcas have a longer lifespan (about 50 years) than males (about 30 years). Similarly, killer whales sometimes slide up onto sand bars or beaches to hunt sea lions. A single pod often has multiple families living together, with each family spanning as many as four generations. Killer whales have also been reported to eat moose, according to Sea World.Orcas use many different techniques to catch prey. After a successful kill they regularly (75% of the time) share their fish, usually family members and particularly offspring. Known by some as “wolves of the sea,” orcas hunt in packs, using their numbers to herd prey into a small or isolated area before attacking. The feeding habits of resident and transient whales of the eastern North Pacific Ocean differ.

Ditch the disposables and make the switch to sustainable products. Orcas are apex predators, at the top of the food chain.

2. When an ice floe is too big to be overturned, Antarctic type B killer whales will swiftly swim side-by-side at the ice floe, diving below the floe at the last second, to create a wave large enough to wash a hauled out seal into the water. Resident whales spend about 60% to 65% of daylight hours foraging for fishes. In pods of resident whales, offspring will stay with their mothers in the same pod for their entire lives. Adult orcas have shiny black backs, white chests and patches of white above and behind their eyes. Transient pods are known to "sneak attack" marine mammals. Take a closer look at these encyclopedia books including information about animal habitats, behavior, and scientific classification. The primary diet of most killer whales consists of a variety of fish such as herring, cod, hake and several other small aquatic species. By emitting clicks and listening for echoes, orcas are able to determine the size, distance, shape, and direction of underwater sea life and objects. Growing calves eat more — as much as 10% of body weight during growth periods. Found in every ocean on the planet, orcas are likely the most widely distributed mammal in the world, next to humans. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. About 30 killer whales attacked an 18.2 m (60 ft.) blue whale. At times killer whales work together to encircle and herd small prey before attacking. Type 2 killer whales specialize in cetacean prey including dolphins, porpoises, and baleen whales such as minke whales. Are you wild about whales? The only exceptions are river dolphins and manatees, according to the IUCN. Killer whales are apex predators, as no animal preys on them. This is certainly no indication of what may happen every time killer whales face great whites, but it does demonstrate the variety of a killer whale's diet. Prey such as these sea lions, may not be safe from killer whales even on land. Globally, killer whales appear to have an extremely diverse diet. Other observed transient hunting techniques include driving and trapping groups of Pacific white-sided dolphins in confined bays and ramming sea lions with their heads or stunning them with tail fluke swats before taking the animal underwater and drowning it. After five hours the pod broke off the attack. Some leaped onto its back. Hunting and Diet Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator.
