Summary:

A large bluish-black devilray with two white crescent-shaped patches on the shoulders in juveniles and newborns (fading in adults), a white underside often with dark patches, a prominent white tip on the dorsal fin, and the inside of the mouth dark. The cephalic lobes are short with black tips, a silvery-grey inner surface, and a white outer surface and side behind the eye. The Japanese Devilray has a subterminal mouth beneath the head, a small white-tipped dorsal fin and a short serrated caudal spine positioned near the base of the very long whip-like tail.

In Australia, this species was previously known as Mobula japanica, a junior synonym (White et al. 2017).

Four male Japanese Devilrays (aka Giant Devilray) filmed pursuing a heavily pregnant female in the Poor Knights Islands, northern New Zealand, March 2017.

Japanese Devilray, Mobula mobular (Bonnaterre 1788)

More Info


Distribution

Recorded in Australian waters from off Fraser Island, Queensland, to off Montague Island, New South Wales, with a juvenile found near the shore at Brighton in Port Phillip, Victoria, April 2020.

Elsewhere, this species is circumglobal in warm seas in coastal and offshore waters. While the Japanese Devilray has been recorded diving to a depth of 1,112 m, the species mostly occurs above a depth of 50 m.

Features

Disc broad, short, head very short; rostral margin not deeply concave; anterior profile of disc wings straight or slightly convex; tail very long, wiry, whip-like, about equal to or longer than disc width (if undamaged), with a stinging spine in most individuals. Mouth broad, subterminal; upper and lower tooth bands ~75% mouth width; denticles dense; brachial filter plates separate on gill arches, 85-95 plates per arch, 18-31 lobes on each plate, terminal lobe leaf-shaped with longitudinal ridges. Dorsal fin small with a rounded white tip and a concave rear margin; short, serrated caudal spine covered in black tissue usually present behind dorsal fin.

Size

Male disc width to 310 cm; female disc width to 240 cm; disc width at birth about 85 cm; adult weight about 115 kg.

Feeding

Filter feeder - feeds mostly on planktonic crustaceans such as krill, euphasids and copepods, along with small fishes.

Biology

Males mature at 200–220 cm disc width (DW) and females mature at 215–240 cm disc width (DW). Reproduction is aplacental matrotrophic (embryos nourished by both yolk and the mother​) with a gestation period of 12 months. Female generally produce a single large pup (though two per litter occur occasionally) of 90–160 cm DW. The reproductive cycle is 1–3 years, with resting periods between pregnancies in some years. Female age-at-maturity is estimated as 5–6 years and maximum age estimated as 20 years.
In March 2017, a mating train comprising a full-term pregnant female and up to four males was observed over a period of 147 minutes in the Poor Knights Islands, Northern New Zealand (Duffy & Tindale 2017).

Fisheries

Mobulids are widely used for their meat, skin, liver oil, and gill plates. The Giant Devilray is a large component of targeted fisheries and a bycatch of many small- and large-scale fisheries in many parts of its range. Much of this catch is unreported or aggregated as Mobula species (Marshall et al. 2019). The gill plates are highly valued in the Traditional Chines Medicine industry.

Conservation

IUCN: Endangered
Mobula species were listed on Appendix II of CITES in 2016.

Remarks

In Australia, this species was previously known as Mobula japanica.
