There are strange fish living in the earth's oceans, one of which is the sunfish, or sting fish. This fish is very large, with an adult length of up to 3 meters and a weight of up to 3 tons. Sunfish have flat bodies and they are the largest known bony fish. They are called sunfish because they like to float on the surface of the ocean and like to turn over on their side to bask in the sun. Sunfish are large but not aggressive fish. The main food source of sunfish is small fish and shrimp, and it also eats jellyfish.

Because of its large size and vestigial tail fin, sunfish are clumsy in the sea and not very good at swimming. As a result, sunfish, whether sharks or killer whales, sea lions, seals, and even tuna, often become food for other hunters who prey on sunfish. When it becomes someone else's delicacy, the sunfish doesn't resist at all. Let alone escape. Not only do other animals bully the sunfish, parasites benefit too. Scientists have discovered through research that at least 50 species of parasites live on sunfish, and even parasites have parasites. But sunfish can also be less adept. Maybe it's because you like to bask in the sun, or maybe it's to get rid of parasites. If sunfish have low survivability and are easily preyed upon by other animals, how can they survive and not become extinct?

The reason sunfish are not extinct is that they are more capable of reproducing than other fish. An adult female sunfish can lay up to 300 million eggs at a time. But only a few people can hatch into fish. And, as the sunfish grow, a variety of predators are targeting them. Even when they grow up, they become very large and cannot live safely. According to local media reports in Yunnan, a strange scene of fishing appeared in Erhai Lake and Xier River in Dali, Yunnan. Many big fish kept jumping on the water surface and suddenly appeared on the bottom of the water. A large number of tourists and passers-by watched. No one knew why this scene happened. .

There are many phenomena of fish turning over ponds, but the most common reason is lack of oxygen in the water. If there is insufficient oxygen in the waters of the fishing ground or waterway, the fish in the water will float on the water and greatly absorb the air. In order to obtain oxygen from the air, some large fish usually do not move near the water surface. There is lack of oxygen underwater, so they often come from The water surface jumps out, and the splashing movement is very large.
