Description

Family Myliobatidae

Atlantic, Indian, and Pacific Oceans. Head elevated above disc; jaws powerful with large platelike crushing teeth in several rows in eagle rays ; eye and spiracles lateral on head; gill openings about length of eye to much longer ; tail much longer than disc; venemous spine(s) present in some; small dorsal fin; pectoral fins reduced or absent opposite the eyes, but with an anterior subdivision that unites below the tip of the snout forming a subrostral lobe in manta rays. Some known for their leaping ability high into the air . Viviparous with 2-6 fully developed young. Plankton-filtering manta rays are among the largest fishes , but harmless.The family Myliobatidae belongs to the Class Elasmobranchii (sharks and rays) and the Order Rajiformes. It contains 7 genera and 42 species. It may be found in Marine and Brackish environments and is primarily Marine. Members of this family are not used in the aquarium trade. Reproductively, most members of this family are bearers. The main mode of swimming of adult fish in this family is rajiform. Members of this family have been dated back to the Cretaceous period. Etymology of this family name : Greek, myleys, -eos = mill , millstone + Greek, batis , -idos = ray

Habitat

Typically found in water with a depth of -4,145 to 0 meters (-13,599 to 0 feet).[4]

Biome: Brackish water, saltwater . Reef-associated .

Ecology: A little known species. Occurs on the inner continental shelf to depths of about 60 m over soft sandy substrate (Compagno and Last 1999). Reproductive biology , age and growth and dietary compositions are unknown for this species. Suspected low fecundity as with other myliobatids, for example Aetobatus narinari and Aetomylaeus nichofii, which bear litters of up to four offspring (Last and Stevens 1994, Compagno and Last 1999).
