Devil ray
Depth: 120 m · Sunlight Zone
The devil ray glides through the water on large wings and sometimes leaps high into the air and slaps back down. With two head fins it scoops tiny plankton into its mouth. The little horns gave it its name, but it is not dangerous at all.
For scientists
Devil rays (Mobula) filter plankton and roll their paired head fins up for swimming but unfurl them into a funnel to feed. They have the largest brain-to-body ratio of any fish and leap spectacularly from the water, probably to communicate or shed parasites. They usually bear only a single pup.
