Its size and strength often make divers afraid, because as soon as it gets angry, as long as its powerful "wings" beat, it will break people's bones and kill people. So people call it "devil fish".
Manta rays look daunting, but in fact they are very gentle and only feed on crustaceans or groups of small fish and shrimp. It has two fleshy feet on its head, and these are its head fins. The head fin turns forward and protrudes freely. Manta rays use these head fins to drive away food and then swallow it into their mouths.
Living habits of devil fish:
Manta rays use their unique big fins to vibrate slowly like spreading their wings and swim leisurely on the bottom of the sea (sometimes watching them "fly" is a pleasure). They sometimes jump out of the sea and sometimes somersault in the air, which is really beautiful. Manta family is the largest inferior foraminifera, with a body length of 8 meters and a weight of 3 tons.
Flat body, strong pectoral fins, similar to wings. They are cruising at sea. There are two narrow ear-shaped protrusions in front of the pectoral fin, which can collect food from the mouth. Teeth are small. Although manta rays are large animals, they mainly feed on plankton and small fish. They often swim near coral reefs and are gentle. In English, it is wrongly called "devil fish" because its shape is scary.
