A larger male of 275 cm TL (without the caudal fin) was observed in March 1998 at Agadir (reported not collected by an IMROP fishery observer). Caught by trammel net (Ref. 109576). The species was known from a few specimens caught in shallow water in Banc d'Arguin sandy shoal (Ref. 114953). Séret, B. and G.J.P.

Resembles Rhynchobatus lubberti in having a similar colour pattern, but differs in having a more broadly rounded snout (similar to that of the shark-ray Rhina ancylostoma (Ref. 109576).
