4 chin barbels and a longitudinal groove in a depression on midline of head.
Western Atlantic: Massachusetts and northern Gulf of Mexico to southern Florida in USA and Mexico.
Adults inhabit continental waters and enters estuaries. Found in turbid waters over muddy bottoms. Males incubate eggs in the mouth (Ref. 205). Commonly captured from catwalks, bridges and piers, particularly in passes and inland waterways. Edible, but generally not consumed (Ref. 7251).
Males carry the eggs in the mouth (Ref. 205).
