Geographic Range [top]

Range Description:This species has been recorded from Florida (USA), through the Gulf of Mexico to the Campeche Bank. It has been recorded as a straggler as far north as Cape Hatteras (North Carolina, USA) (Allen 1980, Burgess 2002). It has been recorded at depths between 20 and 200 m (Burgess 2002), but is more common in deeper waters. Most specimens have been collected by trawlers working in deeper waters (Allen 1980).
