OVERVIEW
IUCN Red List classification.
Atlantic pygmy devil rays (Mobula hypostoma) are present only along the Western Atlantic coasts and islands in tropical and warm temperate waters. They are most commonly observed in groups of 2-10 individuals, with groups as large as 40 being recorded.
The Atlantic pygmy devil rays are nowhere directly targeted by fisheries because of their insignificant commercial value, however some level of mortality to the species derives from bycatch in longline and net fisheries. Unfortunately, this species is likely caught as bycatch in many small-scale fisheries and is now notably absent from many regions of its former geographical range. With a suspected population decline of 50-79% across three generations, this species if now defined as Endangered on the IUCN’s Red List of threatened species.
