Surviving under the Sea
The ocean can be a dark and scary place! Just like animals on land, sea animals have to work hard to keep themselves safe. Many sea animals do special things to protect themselves from danger.
The octopus hides itself by changing its color and texture. It can turn brown, red, or gray. Its texture changes to look like rock or sand. Even when enemies find it, the octopus keeps them away by squirting a cloud of black ink.
The pufferfish stays safe by scaring its enemies. It gulps water and air to puff up like a balloon. This makes it look bigger. It also has spines and can release deadly poison.
The sea cucumber fights its enemies. It releases sticky, white threads. These threads tangle up enemies, such as crabs or fish. If this doesn’t work, the sea cucumber can squirt its organs from its tail to protect itself. The organs have poison in them. The poison hurts animals that try to eat the sea cucumber. Then, the sea cucumber can be safe.
Many sea animals do interesting things to keep themselves out of danger. In this way, they can all survive in the ocean together.
