Pygmy Devilray, Mobula kuhlii (Valenciennes 1841)

More Info


Distribution

Known from the northern half of Australia, from in Australian waters from off Port Hedland, Western Australia, northwards and throughout the Northern Territory, to Moreton Bay, Queensland.

Elsewhere, the species is widespread in coastal waters of the tropical Indo-West Pacific - from the Red Sea and East Africa to Papua New Guinea, Australia, the Philippines and Vietnam.

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

Features


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.

Biology

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

Fisheries

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.

Remarks

In Australia, the Pygmy Devilray has been misidentified as Mobula diabolus which is a junior synonym of M. mobular (White et al. 2017).
