Whenever we pick up the shells sent by the tide on the shore and look at the endless ocean, sometimes it is rough and sometimes it is calm, we always wonder what creatures live under the blue sea. Are there highly civilized "undersea people"? Is there really a mermaid?

I believe everyone wants to ask these questions about the ocean, including me, but I read a book the other day: "

Encyclopedia of biology, this book introduces in detail almost all the marine life we usually hear about, including fish, whales and cephalopods that people usually don't hear about.

I like killer whales best. They are toothed whales with sharp teeth. They may be called killer whales, because they kill many people. They are also called killer whales, because they have high triangular dorsal fins like inverted spears. Black whales are fierce and cruel, and they are born to kill. They usually mainly eat fish, but they also eat human friends-dolphins, seals, seals, walruses and other marine animals, and even blue whales weighing dozens of times. It is also a social animal, which can really be called "underwater wolf"

After reading this book, my deepest feeling is that although the fish in the sea are different in size and shape, they all have their own advantages and disadvantages. For example, Octopus: Although it is weak and easy to be bullied by sharks and whales in the sea, it also has a defense method, that is, when the squid meets an accident or meets an enemy, its first weapon is ink-jet juice. Interestingly, the shape and outline of the black smoke screen laid by cuttlefish are very similar to their own body shape. Ink contains toxins that can paralyze the enemy. The sudden appearance of the black smoke screen left the enemy with the impression that it suddenly became bigger! "The sea is stirred into darkness, and the smoke can last for more than ten minutes. No matter how brave the enemy sees this situation, he will be puzzled and at a loss. At this point, cuttlefish can take the opportunity to escape from danger. Don't say, this move of cuttlefish is really clever. Because of its unique skills, it escaped the harm of many natural enemies. You will understand from here that although some animals are small, their height is not necessarily low! Although people often use pigs to describe people as stupid, scientists have found that the IQ of pigs is still relatively high in the animal kingdom.

Although we have reached the last stage of primary school, the knowledge we have learned is far less than that of an ordinary person. We should not only learn about the ocean, but also fly into space in the future to learn about space!

When we mention the words "twinkle" and "brilliant light", we think of clear night sky and twinkling stars. In fact, this phenomenon will also happen at the bottom of the sea, and the fish at the bottom of the sea will often shine. What happened? Many mysteries of the ocean are waiting for us to uncover. Therefore, we should keep advancing and bravely climb the peak of science.
