During the southwestern monsoon of the Indian Ocean each year, the tide brings nutritious miniature plankton, with manta rays and a large number of bait fish sharing this meal. Photographed by THOMAS P. PESCHAK

The manta ray swims and tumbles to devour plankton, and when its belly is facing the camera, it can't help but be creepy. Photographed by THOMAS P. PESCHAK
The image has a lot of material: the foreground is a flaming red parrot fish patrolling its territory, next to a double-finned sawfish hiding between the tentacles of a sea anemone, and a giant manta ray passing by in the background. Photographed by THOMAS P. PESCHAK
During the southwest monsoon every year, the eastern coast of Baa Atoll in the Maldives attracts about 800 manta rays to feed here, in this photo taken in Hanifauru Bay at Baa Atoll. Photographed by THOMAS P. PESCHAK

The ocean is a place where animals are susceptible to itching, especially the manta ray, which is shaped like a dinner plate, and its body surface is covered with a large number of parasites. Fortunately, there are many small fish that provide full body cleaning services for manta rays, such as the green crescent fish in the picture, and the split lip fish is also a good hand in this regard.

Photographed in the Maldives Archipelago, a young manta ray is drawn to the lights at the stern of a cruise ship and follows it for hours, turning its head and spinning its body like a dance. Photographed by THOMAS P. PESCHAK
