Colour: variable, silver or red to black or dusky, belly always pale; juveniles usually with dark saddles on body; first dorsal fin often with a black spot or blotch; pectoral fins usually with some bands, spots, or blotches; however, a black fin variation may be found in some species that are usually coloured.

Habitat, biology, and fisheries: Searobins are medium-sized benthic fishes inhabiting the continental and insular shelves of tropical and warm-temperate seas usually in depths of 18 to 55 m, range from 9 to 170 m.. They occur on sandy or muddy substrates, rubble, or reef-typebottoms, using the free pectoral-fin rays for support and for search of food. Although most species are not the object of a special fishery, they often enter bottom-trawl catches, sometimes in moderately large quantities. The majority are considered as trashfish, but some of the larger species are used as food. Their flesh is tasty and firm.  Taken in commercial catches as bycatch.

Size: Small, maximum size to 38 cm.

Distribution: Nova Scotia to eastern Florida.
