Fish of the family Rajidae, which includes stingrays and skate, swim by flicking the outer edges of their fins.
One of the most heart-stopping was in a lagoon with stingrays and sharks swimming past them in Daydream Island, Australia.
Like their close relatives the sharks, the 200-odd species of stingrays are boneless fish that boast skeletons made of tough tissue called cartilage.
