What is a killer whale?

Killer Whale

Killer whale is the name of a large porpoise.  It gets its name from the popular belief that it is a blood-thirsty killer.

It has a glossy black back and a white underside.  These creatures often measure 30 feet in length and can weigh 10 tons.

Killer whales get their name from the widely held belief that they will attack any creature in the sea – and, like man, are some of the few animals that kill for sport.

Though they have the reputation as killers, killer whales have not been known to attack swimming men or boats.  Killer whales often hunt in packs, and will attack other whales many times their own size.

Their mouths and throats are big enough to swallow seals, penguins, and young walruses whole.  Only the tusked adult walrus holds the killer at bay.

When killer whales see a seal on a floating chunk of ice, they rush up under the ice and crash into it, knocking the victim into the water.  Killer whales also feed on fish and even sea birds.

What does the blue whale eat?

As big as the blue whale is, it eats only the tiniest plants and creatures in the ocean.  A giant blue whale 100 feet long and weighing nearly 150 tons makes an elephant look small.

The blue whale is perhaps the biggest animal that ever lived.  But as big as the blue whale is, it eats the smallest bits of food it can find in the oceans.

Blue Whale

The blue whale has no teeth, so it can’t chew food, and its throat is so small that it can only swallow small fish.

So it eats mostly tiny plants and sea creatures called plankton that drift about in the ocean.

Instead of teeth, long stringy plates of whalebone hang like curtains from the top of the blue whale’s mouth.  They are used like a strainer.

To eat, the blue whale swims through the plankton with its mouth wide open.  The blue whale then squeezes the water out with its big tongue and swallows the plankton trapped on the whalebone.  It takes barrels of plankton to fill the blue whale’s big stomach.

There are other toothless whales, but some whales have strong teeth, such as the killer whale, and throats large enough to swallow chunks of food. – Dick Rogers
