A researcher has recorded three sharks in a "threesome", or ménage à trois , marking a scientific first.
Hugo Lassauce, a marine biologist and a researcher from the University of the Sunshine Coast in Australia, was snorkeling off New Caledonia, a French territory west of the coast of Queensland, Australia, when he spotted the trio of endangered Indo-Pacific leopard sharks having a bit of fun, according to Storyful. Lassauce recorded the sharks' underwater tango.
