生物学     用語集 (例 epibenthic)

Occur in lagoon and seaward reefs to at least 50 m. Commonly seen in caves and holes in shallow reefs (Ref. 26938, 48637). Juveniles to about 20 cm are pelagic. Adults benthic (Ref. 30573). Solitary and nocturnal that feed on hard shelled invertebrates like sea urchins, gastropods, and hermit crabs (Ref. 9680). Generally common (Ref. 9710). Not normally used as food (Ref. 3717). Reached a life-span of 10 years and a length of 69 cm in the McGinty Aquarium (E. Dashiell, pers. comm 2004), suggesting a preliminary K=0.12.
