  • Myliobatis is distributed in the Eastern Atlantic Ocean, Indian Ocean, and Pacific Ocean. These rays were named because they lack a sting on the tail.


  • Myliobatis is found in sea water. It is viviparous and carnivorous. Feeding feeds on small organisms, crustaceans and molluses. No sexual dimorphism. Although they are bottom feeders, eagle rays frequently swim near the ocean’s surface, occasionally jumping high out of the water in spectacular displays


  • Commonly known as Eagle ray.
  • Body consists of a rhombic disk and narrow tail. Disk is much broader than long.
  • Body is dorsoventrally flattened, divisible into head, trunk and tail.
  • Skin non-tuberculate and devoid of scales.
  • Paired pectoral fins are enlarged but they do not continue with the snout, they cease on the sides of the head and reappear in front of snout as distinct folds, called as cephalic fins paired pelvic fin small and caudal fin indistinct.
  • Compared with other rays, they have long tails, and well-defined, rhomboidal bodies.
  • Eyes large and spiracles present behind eyes on lateral side.
  • Teeth are flat, hexagonal and adapted for crushing.
  • Head is elevated and distinct from disc and contains indistinct snout.
  • Tail is long, cylindrical with a single dorsal fin modified into tail.
  • Eagle rays live close to the coast in depths of 1 to 30 m (3 to 98 ft) and in exceptional cases they are found as deep as 300 m (980 ft).
  • They are ovoviviparous, giving birth to up to six young at a time. 


Some are famous for their ability to leap high into the air from water. They are excellent swimmers and are able to breach the water up to several meters above the surface.


Since this fish has lateral eyes, spiracles and above features, hence it is Myliobatis.
