Manta Ray | National Geographic. Two giant oceanic manta rays feed on plankton. Manta rays are the largest species of ray and live in tropical, subtropical, and temperate ocean waters across the globe.

What do manta rays eat?

Despite their very large size, giant mantas are similar to the largest fishes (whale shark and basking shark) and the largest mammals (blue whale) in that they eat tiny plankton. They constantly swim along with their large mouths open, filtering plankton and other small food from the water.

Do manta rays eat humans?

Manta rays pose no danger to humans. They are calm and delicate animals with no aggressive behaviours and are not predatory in nature. These gentle giants are filter feeders, gliding through the ocean on their massive wings feeding on microscopic plankton near the surface of the water.
