Spines are larger toward front and disappear with age on rear parts of tail. Few scapular spines. Group of spines in front of and around each eye. Adults have 1 middorsal row of many small spines, 1 row of small spines on each side, middorsal row of spines extend forward on disk to area behind eyes. Young have 2 pale crossbars on tail, each outlined by a dark blotch or band. Snout pointed [17658]. Upper surface pale brown with numerous obscure darker spots, irregular pale markings.

Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086]. Inhabits soft mud and clay bottoms of the deeper troughs and basins, sands, sands and shells, gravel and pebbles of the offshore fishing banks [199]. Salinity ranges from 32.6 to 35.4 [199]. This species is confined to deep water. No occurrence has been found in less than 8 m of water [199]. Feeds on decapod crustaceans and euphausiids, with mysids being more important. Parasites of the species include blood parasite, Haemogregarina delagei (protozoan) and Zyxibothrium kamienae (cestode) (Ref. 5951).
