The recent BBC series, “Shark” features an amazing sequence of mobula rays (Mobula munkiana) jumping and breaching. Filmed in the Gulf of California, Mexico, the rays jump some 6ft (2m) into the air and then seem to land awkwardly, creating a big splash. There are several theories as to why the animals do so, ranging from feeding, courting, communicating, and ridding themselves of parasites, but there is no definitive answer which suggests that it may have multiple causations.

The BBC Shark series is now available on iTunes.
