More Info


Off Port Hedland, Western Australia, around the tropical north to Sydney, New South Wales. Elsewhere, the species is widespread in coastal waters of the tropical Indo-West Pacific - from East Africa to Papua New Guinea, north to the Philippines, and south to Australia. 

The Pygmy Devilray is pelagic in coastal waters around continents, and has not been recorded from oceanic islands.


Disc broad, short; tail shorter than disc width with no stinging spine; head relatively long, mouth on underside, cephalic lobes prominent with a deeply concave rostral margin.


Devilrays typically give birth to a single pup per litter with a gestation period of 1–3 years.


This species is taken in both target and bycatch fisheries in many parts of its range. Mobulid rays are targeted for their branchial filter plates for use in traditional Chinese medicines.


White et al. (2017) considered Mobula eregoodoo to be a junior synonym of M. kuhlii. In Australia, the Pygmy Devilray has been misidentified as Mobula diabolus, a junior synonym of M. mobular (White et al. 2017).
