Description

The cownose ray (Rhinoptera bonasus) is a ray of the family Myliobatidae from the western Atlantic. The species owes its name to its cleft, cow-nose-like snout and has broad, wing-like pectoral fins with which it 'flies' gracefully through the water. It lives on the continental shelf, enters bays and estuaries and sometimes forms huge schools. The diet consists mainly of benthic invertebrates and mollusks, which it crushes with flat tooth plates, sometimes damaging seagrass beds. The tail bears a spine. Owing to overfishing and slow reproduction the species is considered Vulnerable (VU). The disc reaches about 1.2 metres across.
