Manta ray swimming

The manta ray (Manta birostris) is one of the largest fish in the ocean, known for its cephalic fins and graceful swimming in tropical waters.

About this subject

Manta rays belong to the family Mobulidae and are close relatives of sharks. They can reach up to 7 meters in wingspan and weigh over 1.3 tons. Unlike venomous stingrays, mantas lack a stinger. They feed on plankton, filtering water through their gills while swimming with an open mouth. Their cephalic fins, shaped like horns, help funnel food. They are found in all tropical and subtropical oceans, often at upwelling sites like the Fernando de Noronha Archipelago and Mozambique. Mantas have one of the largest brains among fish and exhibit complex behaviors such as jumping and circle swimming during feeding. Unfortunately, they are threatened by bycatch and the trade of their gill plates in traditional Asian medicine. Since 2013, they are listed as Vulnerable by the IUCN. Observing them while diving is a transformative experience.
