The sunfish looks very strange. Its body is short and backward, its dorsal and anal fins are opposite and very high, and its tail fin is very short. It looks like it has been cut off with a knife. Therefore, its common name is also called head fish.
The sunfish swims slowly. It lives in tropical seas, and is often surrounded by many luminous animals. When it swims, the luminous animals on its body will emit bright light, and it looks like a bright moon from a distance, so it is also known as the "moon fish". The top-heavy body of the sunfish is very suitable for diving. It often dives into the deep sea to catch deep-sea fish and shrimps for food.
The sunfish is clumsy and not good at swimming, so it is often eaten by other fish and sea animals in the ocean. The reason why it is not extinct is its strong reproductive power. A female fish can lay 300 million eggs at a time, making it the best fish mother in the ocean.
Sunfish are found all over the world's oceans. There are three species of sunfish along the coast of my country, namely sunfish, yellow-tailed sunfish, and spear-tailed sunfish.
