Etymology: Chilomycterus: Greek, cheilos = lip + Greek, mykter, -eros = nose (Ref. 45335). More on author: Linnaeus.
Environment: milieu / climate zone / depth range / distribution range

Circumglobal: Gulf of Mexico, Atlantic, Indian and Pacific oceans.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 69.7 cm NG male/unsexed; (Ref. 89467); common length : 30.0 cm TL male/unsexed; (Ref. 26999)
soft rays: 11 - 14. Adults grey to brown with a black gular band and small black spots on upper surfaces and fins; pelagic juveniles blue with dark spots above, the spots descending to belly (Ref. 4423).
Adults found in reefs and over soft bottoms to depths of 100 m, but may occur deeper in the tropics (Ref. 30573). Often found washed up on beaches. Known to brace themselves against the substrate to sleep at night (Ref. 4930). Appear to be active during the day. Juveniles often with floating weeds (Ref. 48637). Solitary. Juveniles pelagic in oceanic surface waters (Ref. 30573). Feed on hard-shelled invertebrates. Not usually marketed.
