Korte beschrijving
Morfologie | Morfometrie
Moderate-size moray with a pattern of distinct small, round, overlapping dark brownish to purplish-black spots on white or pale yellow background (Ref. 26938).
A benthic and solitary species (Ref. 26340) abundant in shallow rocky and grassy areas and on coral reefs; less common in turbid bays or harbors. Its bite is very dangerous (Ref. 5217). Active during the day, sometimes together with other predators. Feeds on fish and crustaceans (Ref. 42064). Usually seen with its head protruding from a hole and the rest of its body concealed (Ref. 26938). Observed to be unusually aggressive towards man (Ref. 86997). It has been traded as aquarium fish at Ceará, Brazil (Ref. 49392). Marketed fresh and salted (Ref. 5217).
