Fungia repanda
Dana, 1846
Description: Polyps are circular, up to 300 millimetres diameter, thick and flat or strongly arched. Septa are almost equal at the polyp perimeter. Septal teeth are fine but clearly visible. There are no tentacular lobes. The undersurface has pits between the costae. Costal spines are granular. Tentacles are usually slightly extended during the day giving the polyp a speckled appearance.
Color: Usually brown with pale tentacles.
Habitat: Reef slopes and lagoons.
Abundance: Common.
Similar Species: Fungia scabra, which has finer septal teeth. See also F. concinna and F. fungites.
