Whales

Whales are huge mammals. They live in the ocean. They mostly eat tiny little creatures called plankton.

Narwhal whales are medium sized and have teeth. They have one long tusk which can be as long as 1.5 to 3.1 metres long, and they have long flippers. They grow as big as 3.95 to 5.5 metres and weigh 800 to 1,600 kg. They are blackish-brown and white.

They only live in the Arctic Ocean. They can dive very deep, especially in winter when there is ice in the ocean.

Narwhal whales eat fish, such as cod, cuttlefish, squid and shrimp. They hunt by swimming close to their prey and then sucking it into their huge mouths.

They are not really dangerous to humans but humans have hunted them too much so now there are not many of them left.
