TAXONOMY
Kingdom: Animalia
Phylum: Cnidaria
Class: Anthozoa
Order: Scleractinia
Family: Trachyphylliidae (Solitary stony Coral)

Genus/species: Trachyphyllia geoffroyi

GENERAL CHARACTERISTICS: Name comes from Gr: trachys (rough) and phylon (leaf) as it looks like a leaf lying on the substrate. Trachyphyllia are secondarily free-living, usually beginning growth as a single polyp attached to a hard surface. Later it breaks off, and is found detached on sandy or muddy bottoms. Color may vary with depth or substrate: pink to red,
brownish, gray, green, or blue, even multistreaked and iridescent. Fleshy polyps extend well beyond the margin of the stony skeleton.

DISTRIBUTION/HABITAT: Found in the Indian and Western Pacific oceans on sandy bottoms among seagrass in the outer feel margins.

DIET IN THE WILD: Nutrition from photosynthetic zooxanthellae; also microplankton and other small food bits. Tentacles extended in low light or at night to capture plankton.

CONSERVATION: IUCN RED LIST Near Threatened (NT)

REMARKS: Tangs and angelfishes like to nip and feed on them.
At night their soft tissues may swell to remove debris and sand that accumulates during the day.
