Rays are very similar to rays because they both have flat bodies. Juvenile rays feed on animals that live on the bottom of the sea, such as crabs and lobsters. When I grow up, I mainly prey on mollusks such as squid. When hunting, rays mainly hunt by smell. When rays lie on the bottom of the sea, they try to avoid inhaling sediments by using special closed breathing methods. When rays breathe, water is inhaled through the pipe overhead and finally flows out through the cracks in the cheeks of the abdomen.

It is distributed in most waters of the world, from tropical to near-Arctic waters, from shallow water to deep water below 2700m, and mainly lives in the East China Sea and South China Sea of China. Okinawa, Japan is one of the important settlements of rays, which is listed as the main tourist attraction by the local government. The aquarium here has a special area for people to watch at close range.
