Named for their appearance, which can resemble a baseball glove, the Leather coral, or Toadstool coral is found in various shades of brown, green, or yellow with white or gold polyps. It can be difficult to identify leather corals because many of them are similar in appearance. As they grow older, they develop a folded appearance. Like other soft corals, Leather corals incorporate tiny, single celled algae, known as zooxanthellae in their tissues.
