features
Zanobatus maculatus becomes about 36 cm long. The body disc is wide, almost circular and rounded at the front end. The back is brownish to greenish-brown and patterned with densely packed dark spots of different sizes and with small, white dots. The spots get smaller towards the edge of the body disc. The white spots are often arranged in a ring around the dark spots. The ventral side is beige, orange or reddish-brown. The edges of the paired fins are dark on the ventral side. The nasal and gill regions on the underside are also dark. There is a dark spot on the pelvic fins. The thick tail is beige to orange with some dark spots on the edge. It is almost round in cross section. Only the bottom is a bit flattened. The nostrils are large and connected to the mouth by two pits. The mouth with thick lips is small and straight. The skin of Zanobatus maculatus is densely covered with small placoid scales. They have arrow-shaped tips on the back and flattened on the belly. The scales are arranged in parallel rows on the trunk and in concentric rings on the pectoral fins. Between the neck and the first dorsal fin are 22 to 23 thorns, between the first and second dorsal fin there are one to four thorns. In addition, some are on the caudal peduncle and, in some specimens, on the outer pectoral fins. Compared to Zanobatus schoenleinii , Zanobatus maculatus is smaller and more thorny. Zanobatus maculatus has 54 to 64 rows of teeth in the upper jaw and 36 to 44 vertebrae in front of the first dorsal fin.
