Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 14-17; Spine anali 0; Raggi anali molli: 14 - 16. Body robust; teeth united in each jaw but without a central division; body covered with long, sharp spines, folded backwards when body not inflated; 16 to 20 spines between snout and dorsal fin; dorsal region of caudal peduncle spiny; back, flanks and fins light brown with numerous dark spots; belly spiny (Ref. 55763). Spines long. Body grayish tan, with small black spots, but no large dark blotches. Belly white, surrounded by dusky ring (Ref. 26938). About 20 spines in an approximate row between snout and dorsal fin (Ref. 13442).

Biologia     Glossario (es. 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.
