coral Oulastrea crispata Family Faviidae updated Oct 08 Where seen? This hard coral with a black-and-white skeleton is among the most commonly encountered of our hard corals. Even rather 'beat up' shores may have small colonies encrusting rocks and stones. Oulastrea crispata is the only species in the genus. Features: Colonies about 10-15cm, sometimes much smaller. Corallites (about 0.5cm) with white radiating walls on a black background. The background remains black even after the colony is dead, thus its common name. The polyps have thin tentacles and are brownish and sometimes with a greenish tinge. The colony tends to be encrusting, sometimes a small boulder-shape.This hardy coral grows even where it is often exposed to air at low tide and in muddy waters. |
