Brotula is a genus of marine fish from the male bearded family(Ophidiidae). It occurs worldwide in tropical and subtropical oceans.
features
Brotula differs from all other male beards by the three pairs of barbels on the snout and lower jaw. The fish are elongated and reach maximum lengths of 15 to 115 cm. Your body is completely covered with small round scales. The number of Branchiostegal rays is eight. The narrow, throat-shaped pelvic fins are supported by only two fin rays. On the first gill arch there are four functional gill trap rays or less. The middle tooth plate on the basibranchial (bone at the base of the branchial arch) is missing.
Way of life
Adult Brotulas live benthopelagic down to depths of 650 meters. Young fish are often seen in reefs. Smaller, silvery juvenile fish also epipelagic in the open sea.
