Killer Whale Facts For Kids

Because of their large size, big diet and amazing jumping abilities the killer whale is one of the most amazing and well-known marine mammals in history.

Although these marine mammals are commonly referred to as “killer whales” they actually belong to the dolphin family which is made up of around 40 different species of dolphin.

When you combine the killer whale with all of the other marine mammals in the cetacean family the killer whale makes up one of around 90 known species of cetacea.

For those unaware of what cetaceans are the cetacean family is a groups of marine mammals that are made up of all species of whale, dolphin and porpoise.

When it comes to how this marine mammal received its name the word “killer whale” comes from the fact that these marine mammals are the largest of all the dolphin species and as big as some whales.

They are also one of the most amazing hunters out of all of marine mammals.

In fact when compared to all of the other whales, dolphins and porpoises the killer whale has the most diverse diet of all known cetaceans.

When fully grown the killer whale can reach lengths of 26 ft. long and weigh over 6,000 pounds, however the largest measured killer whale grew to around 32 ft. long and weighed around 10 tons!

Killer whales are amazing hunters

When it comes to finding food to eat the killer whale can often be seen working together with other killer whales using teamwork to capture their prey.

In one strategy a group of killer whales may circle around a group of fish forcing them into a tight ball while another killer whale swims underneath them to push them towards the surface of the water.

The killer whales will then stun the fish by slapping them with their tails and then take turns swimming though the group and consuming the petrified fish.

Another strategy killer whales are known to use when hunting their prey is to tire their prey out.

When killer whales hunt for other marine mammals such as dolphins they will take turns chasing the dolphin until it is too tired to swim.

Once the dolphin is tired out the killer whales will then move in to capture prey.

When hunting for penguins or sea lions killer whales have been observed leaping onto icebergs in an attempt to catch their prey off guard and when hunting sharks killer whales will flip the shark over so that it cannot attack them.

As stated earlier the killer whales can be pretty diverse depending on where they live.

Some killer whales are known to consume various species of fish and squid as the main part of their diet while others may consume marine mammals such as seals, sea lions, walruses, penguins, dolphins and whales.

In fact some of the most interesting foods killer whales have been known to consume include:

  • Moose
  • Birds
  • Whales
  • Polar Bears

In addition to hunting for food together killer whales are also capable of echolocation.

By using echolocation killer whales can search for food using sound.

This allows them to find food even when they are hunting at night and cannot see.

Killer whales love their family

When it comes to family killer whales are extremely family oriented and as many as four generations of family members may be seen traveling together.

In fact a single pod could consist of children, their parents and their grandparents.

Even after the children reach adulthood they can still be seen traveling alongside their mother.

Killer whales are extremely intelligent mammal and can learn complex tasks from observing and practicing what their peers do.

Killer whales have been observed teaching each other how to communicate, how to hunt and how to survive in the ocean.

Communication among these large animals involves creating high pitched clicks and whistles which they use to share their thoughts and feelings.

Killer whales can communicate many different things to one another such as that they have found nearby prey, that their is danger in the area or that they want to play.

How killer whales became so popular

In the 1960’s killer whales made their huge debut splash at marine shows.

One of the oldest known performing killer whales “Shamu” is still widely known today despite the fact that she has not been in performance for several decades.

Part of her fame came from her being one of the first killer whales to be successfully captured and being the first killer whale to survive living in captivity for more than 13 months.

Today killer whales have become a main attraction to several aquatic theme parks performing flips and various acrobatic stunts and displaying their talents to thousands of people each year.

They have also become popular in movies and television shows often being depicted as friendly intelligent marine mammals that are capable of performing amazing feats.
