Overview

Found singly, or in small squadrons, usually along coastlines but sometimes in oceanic waters. These beautiful creatures are a threatened species.
They feed on planktonic crustaceans.

They belong to the family of Devil Rays who are identified by head fins, which when rolled up 'look like horns' and when unfurled they act like a funnel for the mouth when feeding on plankton and fish larvae. they are filter feeders,found at cleaning stations, along reef edges and at the surface.

These are huge, graceful rays and a wonderful sight. When one leaps, it comes down flat and its body hits the sea with a loud crash. With no teeth or grinding plates to bite with and no stinger in the tail, speed is their defence.
