Manta rays do not form schools in the traditional sense, as they are generally solitary creatures. However, they may congregate in certain areas to feed or to mate. These congregations are usually temporary and are not considered to be schools. Manta rays are known for their graceful swimming and can often be seen gliding through the water in search of food. They are filter feeders and consume large amounts of plankton and small fish. Despite their size, manta rays are harmless to humans and are popular among scuba divers and snorkelers for their beauty and docile nature. Manta rays are found in tropical and subtropical waters around the world, and there are two recognized species: the reef manta ray and the giant manta ray. Both species are threatened by overfishing, pollution, and habitat destruction, and conservation efforts are underway to protect these magnificent creatures.
