Nevertheless, for whatever reason, thousand flying rays off the coast of California remains a breathtaking show. This footage shows mobula rays jumping above water, up to 2 meters high. So know, let me ask you the same question, why do rays jump? Share your suggestions in the comment section. However, clownfish are still unknown to the general public.

But there is many hypothesis proposed by expert : Those jumps could help rays to get rid of parasites and remoras also called suckerfish, fish that use suction cup to stick to bigger animals that made them suffer.
By doing big leaps, school of rays may communicate with isolated individual trying to indicate their location in order to help them to join the group.

But scientists are not sure exactly why they do it. The rays have large, flat, diamond-shaped bodies and long fins, allowing them to glide through water - and also through the air. Huge groups of the fish regularly gather together to leap out of the sea and launch themselves into the air.
They can jump around two metres out of the water before flopping back down with a splash. Groups of them have been spotted behaving this way for hours at a time, especially off the coast of Mexico. There are nine species of mobula ray, and all of them jump, although they may do it for differing reasons.
It is thought that the behaviour is a method of communication, though scientists have not yet worked out the exactly what's going on. It could be a display to attract more rays into a mating event, or it could be a way of hunting as a group. Mobula rays closely related to sharks and are part of the family Mobulidae, which also contains two species of manta ray. Rays in this family are large and can be found all over the world, in both tropical and temperate waters.
There is still plenty that experts don't know about the family, including details of their evolutionary history and population structures.
Mobula rays tend to be shy and avoid divers, so studying them can be difficult. We do know that they filter-feed, meaning they strain plankton out of the water using their mouths, and that shoals of them often gather together in huge numbers.
Ray populations plummeted in the Gulf of California, off Mexico, when fishermen began targeting them in the s. Within a few decades some ray species in the area were nearly wiped out. Numbers are still low in that area despite new legislation protecting the fish.
Targeted fishing damages population levels quickly because the rays take several years to reach sexual maturity and usually only give birth to one pup at a time after long pregnancies.
