Morfologia | Morfometria
Dark brown with numerous yellow dots, smallest on head and largest toward end of tail where they are irregular and confluent (Ref. 13442). Stout moray with a short blunt snout. Tip of tail always pale, usually deep yellow in life. Posterior nostril in short tube (Ref. 26938).
A benthic and solitary species (Ref. 26340) inhabiting coral reefs and rocky shorelines. Usually at depths of 60 m (Ref. 26938). One of the most common and easily recognized morays of the West Indian reefs, active during the day and sometimes hunting together with other predators (Ref. 42064). This species has been called Muraena miliaris (Ref. 26938).
