They prefer unpolluted southern seas. Their coral branches lose their color and deteriorate in dirty water.
Corsola is a small, pink, roundish Pokémon with branch-like growths on its back, which are similar to coral. There is a smaller, blunt horn on its forehead, and it has black, oval eyes. It has a white underside, which speckles towards the sides. Its four legs and two arms are blunt and stubby. Found in the warm shallow waters of southern seas, Corsola requires clean water to live. If its habitat is dirty, the growths on its back become discolored and degenerate. However, when it is healthy, its growths regularly shed and grow back. It is able to regrow them over the course of a single night. It forms large social groups.
