Verrucae


On first inspection the genus Pocillopora (p. 2 of the Coral Finder) has lumpy corallites, but a closer look immediately shows that the corallites are tiny flat structures scattered over the colony surface.  The bumpy texture is formed by verrucae; lumpy skeletal growths which give Pocillopora its distinctive appearance.

Verrucae are mounds of skeleton on the colony surface that are often covered in corallites - the genus Pocillopora.
