The Octopus is one of the most clever fish in the sea. An octopus can fill a room sometimes. It is very fast and ferocious. With its tentacles it can grab, suck and choke very quickly.

It prefers to eat sea lions, dolphins and other sea animals. It is now known that killer whales, known as Orcas, will attack and kill a great white shark. The white shark makes its home in both the Atlantic and Pacific oceans. This shark is usually found in deeper water. However, a white shark will sometimes go to shallow water quite close to the shore, where it finds most of its food.
You may not know this but whales are actually mammals, not fish! Yes, although they may look like fish, they are hot blooded animals. They carry their babies in their stomachs for many months and give birth to them like humans do. The mothers are usually called cows and the babies are called calves. Like you, they breathe from the air and need to come up to the surface of the ocean every now and then, as they are unable to breathe underwater. Some whales, like the Sperm Whale, can stay underwater for nearly an hour before coming up to the surface. Other whales can stay longer or less, depending on their type. There are many types of whales in the sea, with the biggest and most famous being the Blue Whale.
