Aerial displays by mobula rays

I don’t have a photo of mobula rays, which is what this post is about, so here is the tail of a whale. Someone sent us this link of mobula rays cavorting in the ocean. They are found in tropical and warm temperate waters and are known for their love of breaching. There are a number of species which have disc widths that vary from 1.1 metres to 5.2 metres (3.6–17.1 ft). The largest are only slightly smaller than the better known manta rays which can reach 5.5 to 7 metres (18 to 23 feet). Most species lack a tail stinger or, if they have one, it is encased. Only one has a free stinger. Parts of this clip remind me of a ballet performance although not so much the belly flops. Both sexes display this leaping-out-of-the-water behaviour either for sheer pleasure or to catch the eye of the opposite sex. I guess some creatures are impressed by belly flops.
