Johtonian Corsola is not known to evolve into or from any other pokémon. 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 oval-shaped black eyes and a smiling mouth. It has a light blue underside, which speckles towards the sides. Its four legs and two arms are blunt and stubby. Smaller pokémon like Horsea and Luvdisc are sometimes sheltered by Corsola's branches and even offer it protection from foes. Corsola's horn is a prized material, commonly used for jewelry and carving, as seen in the pokémon the Series episode A Corsola Caper!. Some people keep Corsola branches as charms to promote safe childbirth. Corsola's branches glitter very beautifully in seven colors when they catch sunlight. If any branch breaks off, this pokémon grows it back in just one night. 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. Occasionally, these groups get so large that people may live atop them, as is the case in Pacifidlog Town.
In the Alola region, Mareanie and Toxapex are natural predators of Corsola, preying on its branches. If pursued by them, Corsola will sometimes snap its own branches off as a diversion. Conversely, Mareanie and Toxapex do not prey on Corsola in the Galar region, having not developed a taste for its branches. See also:
