ข้อสังเกต | Occurs in clear lagoon and seaward reefs from 0.5 to at least 30 m. Found in pairs or small groups and nests near bases of dead corals, often on clumps of algae. Monogamous (Ref. 52884, 48637). Feeds exclusively on Acropora polyps and is therefore restricted to areas of abundant coral growth. Feeding takes place throughout the day becoming less towards the evening (Ref. 46144). Pairs are commonly encountered among branching or "tabletop" corals (Ref. 54301). Tend to have protruding snout and teeth that project from small mouth which permit them to snip off scleractinian coral polyps despite the surrounding calcareous armor (Ref. 59308). |
