Photo and video of conjoined twins
A pair of conjoined gray whale twins was found dead in Guerrero Negro, one of the gray whale calving lagoons on the Pacific coast of Baja California. This is a very rare event to photograph. This link has some footage and some details. The calves did not survive, but may have been full-term. http://www.grindtv.com/outdoor/nature/post/conjoined-gray-whale-calves-discovered-in-baja-california-lagoon-find-could-be-a-first/
