Its skeleton is long and thick. It has no hind limbs, only contains the skull, ribs, bone structure of the front fins and a backbone that consists of 52 vertebrae.

What does a killer whale use its tail for?

So given the relatively poor acceleration and manoeuvrability of such a large animal as a killer whale, compared to a small fish like the herring, the whale's use of its mobile tail fluke as a herring-swat is a highly efficient way of gathering food.

Why are killer whales so important?

Ecosystem Roles

Killer whales are top predators in most marine ecosystems and impact the populations of common prey, such as seals and sea lions in breeding areas.

Is Killer Whale a vertebrate?

A vertebrate is an animal with a backbone. (An invertebrate is an animal without a backbone.) Fishes, amphibians, reptiles, birds, and mammals, including humans, are all... Killer whales, also called orcas, are mighty hunters of the ocean.

How strong is an orcas bite?

For animals living today, the Orca is the largest animal that uses it's teeth to kill and dissect prey, and has the strongest unconformed bite force of nearly 20,000 pounds per square inch.

Why do orcas need to stay wet?

Without the water to keep them cool, they overheat and lose too much water via evaporation from their lungs. Whales can also drown as the tide comes in because they are lying on their side and the water covers their blowhole before it's deep enough for them to swim free.

Can orcas survive out of water?

Naturally, whales are sea creatures and can live the best in the ocean. If they ever are on land, they can survive only a couple hours. ... A lot of whale die when then are on land because they cannot support their own weight when out of the water.

Do Orcas breathe oxygen?

How do Whales Breathe? Whales have lungs they use to get the oxygen they need by breathing air (like humans). But instead of breathing through their mouth, they breathe through their nostrils, called blowholes, located on top of their heads.

Are killer whales endangered yes or no?

All killer whales are protected under the MMPA and the Southern Resident population is listed as an endangered species under the ESA. We have focused our conservation efforts to help rebuild endangered and depleted populations on the West Coast and Alaska.

What would happen if the blue whale went extinct?

Humans selectively fish out the largest species from Earth's oceans, causing their populations to dwindle. If that weren't alarming enough, the extinction of those animals—think great white shark, bluefin tuna, and blue whale—could ripple down the food chain and spell extinction for entire ecosystems.

What are orcas closely related to?

The closest-living relatives of orcas are hippos, but a modern example of what their ancestor may have been like is the chevrotain, a small deer species that dives into water when threatened, hiding from predators below the surface.

How have killer whales evolved?

Geneticists have deciphered the brief history of the killer whale: the predator that exists in every ocean but has evolved over the generations to hunt in disciplined packs, and specialise in a range of diets. ... Some groups of Orcinus orca live on a diet of fish, others on mammals, some on birds and reptiles.
