Aetobatus

Aetobatus (from Ancient Greek ἀετός (aetós), meaning "eagle", and βάτος (bátos), meaning "ray") is a genus of eagle rays native to the Atlantic, Pacific and Indian Oceans. It was formerly placed in Myliobatidae, but is now placed in its own family Aetobatidae based on salient differences from myliobatids, especially the pectoral fins joining the head at the level of the eyes.

==Description== This genus is diagnosed by a large adult size, which is around wide and largely consisting of a wing-like rhomboidal "disc" (pectoral fins). The trunk is broad, depressed, and thick. The head protrudes forward anteriorly, is narrow, and elevated above the disc, which connects with the head at the level of the eyes. The spiracles are located dorsally and angles towards the sides. The mouth is broad, located ventrally, contains a single tooth plate row, and is surrounded by sensory pores and papillae. The internasal flap possesses a deep "V" shaped notch. A single dorsal fin arises near the base of the very long whip-like tail, which is armed by one or more stinging barbs.
