Etymology: Malacanthus: Greek, mala = a lot + Greek, akantha = thorn (Ref. 45335). More on author: Guichenot.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 5 - 50 m (Ref. 30874), usually 14 - 45 m (Ref. 37816). Tropical; 22°C - 28°C (Ref. 27115); 32°N - 32°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 32.0 cm TL male/unsexed; (Ref. 30573); common length : 26.5 cm SL male/unsexed; (Ref. 37816)
Inhabits barren, open areas of outer reef slopes. Occurs in pairs over rocks or sandy areas adjacent to reefs (Ref. 5213). Usually lives in a burrow of their own construction, often under a surface rock on sand (Ref. 48635). Has pelagic stage to at least 5 cm, hence smaller juveniles are not seen on the substrate (Ref. 48635). Benthic and Benthopelagic (Ref. 58302). Marketed fresh (Ref. 9119). Minimum depth reported not from Ref. 30874.
