Porites compressa

Dana, 1846

Colonies may form large patches of reefs. Branches are cylindrical and commonly fuse. Growth-forms and corallite characters are extremely variable so much so that single reef patches are composites of distinct races.

Colour: Mostly dull greys and browns.

Habitat: Shallow protected reef and lagoon environments.

Abundance: The dominant coral in Kaneohe Bay, Hawaii.

Similar species: Porites cylindrica , Porites harrisoni

Taxonomic note: Taxonomic note: Porites duerdeni (Vaughan, 1907) may be a valid Hawaiian endemic species like P. compressa. It is described as having thicker branches and has minor corallite distinctions. Source reference: Veron (2000). Taxonomic reference: Vaughan (1907). Additional identification guide: Maragos (1977).
