Short description

Dorsal spines (total): 0; Anal spines: 0. Snout short, its tip somewhat pronounced; upper surface entirely spinulose, about 8 thorns generally in a complete row around inner margin of eye and a triangle of thorns on nape or shoulder region; underside with prickles only on snout, between gill-slits, along abdomen, and at anterior margins of disc; tail only slightly longer than body; upper surface reddish-brown to dark brown with 4-6 creamy spots on each wing, underside white (Ref. 3167).

Found in offshore shelf waters and on upper slope, mainly around the 100 m line (Ref. 3167). Depth range from 70-275 m (Ref. 03167), and from 463-676 m in eastern Ionian Sea (Ref. 56504). Feed on all kinds of bottom animals (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 8.3-9.2 cm long and 4.6-5.3 cm wide (Ref. 41303, 41251, 41311).
