Javanese cownose ray  (Rhinoptera javanica)

Biology

This species is sometimes found in extremely large groups, with schools of up to 500 rays having been reported (2) (3). Feeding on a diet of clams, oysters and crustaceans (2), the ray uses its large plate-like teeth to crush the shells of its prey (3). Reproduction is ovoviviparous, with live young being ‘born’ after they have hatched inside the female (2).
