Description

Myliobatis species can reach a width up to about 1.8 m. Their bodies consist of a rhomboidal disc, wider than long, with one dorsal fin. The head is broad and short, with eyes and spiracles on the sides. The tail is slender, with one or two large spines at the base, without tail fin.

The teeth are arranged in the lower and upper jaws in flat tooth plates called pavement teeth, each consisting of about seven series of plates, which are used to crush clam shells and crustaceans.

Biology

Myliobatis species are ovoviviparous. Their gestation lasts about six months, and a female produces four to seven embryos. Myliobatis species mainly feed on molluscs, bottom-living crustaceans, and small fishes.

Habitat

Myliobatis species live in warm, shallow waters. Adults prefer sandy shores, while juveniles can usually be encountered offshore.
