Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 110 m (Ref. 26938), usually 10 - 50 m (Ref. 5217). Tropical; 41°N - 33°S
Western Atlantic: Canada (Ref. 5951) to New York (USA), Bermuda, and northern Gulf of Mexico to southern Brazil.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 26340); common length : 12.0 cm TL male/unsexed; (Ref. 5217)
soft rays: 58 - 69. Light tan to light gray with irregular pale rings or rosettes, some of which are dark-edged; scattered small dark spots and three large blackish spots along straight portion of lateral line, the middle one the best defined (Ref. 13442).
Inhabits sandy areas with coral rubble or seagrasses, usually near patch reefs (Ref. 9710). Shallow coastal waters to depths of 110 m (Ref. 26938). Lies motionless on the bottom, moving only when frightened (Ref. 9710). Larvae are attracted to lights at night but are difficult to see because they are transparent (Ref. 26938). About one-third of the diet consists of fishes; the rest of its food is crustaceans: crabs, shrimps, amphipods, and mantis shrimps (Ref. 13442).
