Ecology of Thelenota ananas
Main Ref. Conand, C., 1998
Remarks A common reef species mostly found from near the surface to a depth of 25 m; generally occurs on hard bottoms, large rubble and coral patches, on reef slopes and near passes. Symbiotic pearlfish (Carapidae, Ophidiiformes) are often found in its general cavity (Ref. 122); common on exposed sandy bottoms or rubble areas of the reef fringe from 10 to 30 m (Ref. 800). Also found on seagrass (Ref. 122153). Associated with commensal pearlfish that live in the body cavity (Ref. 800). This is also found in lagoons at depths up to 30 m on clean sandy bottoms or on slabs near large coral heads. It feeds exclusively on calcareous alga Halimeda sp. (Ref. 118).
