Short description Morphology

The head and neck are moderately thin. Cream, grey or pale brown cross-bands with paler interspaces are wider dorsally and taper on the sides. Incomplete secondary dark bands between the primary ones may be present, with dark-centered scales on the paler parts of the body. Head is pale, bandings on the tail. More obscure than those on the body and in older adults. Head shields are irregular and fragmented in adults. Those around the eye are raised posteriorly to form spines. Prefrontal scales absent.

Biology     Glossary (e.g. epibenthic)

Relatively found in tropical continental shelf waters (Ref. 78651), not often close to shore (Ref. 78391). Often seen on the surface in reef waters (Ref. 2357) and open waterways (Ref.75894). Inhabits loose sandy-silty bottoms, seagrass beds, solid substrates and in a lagoon (Ref. 2352). Sometimes nocturnal (Ref. 2352). Feeds on a variety of fishes (Ref. 2357) like gobies (Ref. 98471). Also feeds on commensal shrimps of the genus Alpheus sp. (Ref. 2352).
