Oceanic manta rays are the largest species of ray in the world, with a wingspan of up to 26 feet. Despite their immense size, they are completely harmless to divers - they have no barbs to speak of, unlike stingrays, and spend their time filtering the water for plankton with the help of their cephalic lobes (the big paddles on each side of their mouths). Socorran mantas have grown very used to divers, and often seek out our bubble curtains seemingly because they feel good and may help clear away parasites!
