It was a very rare occurrence indeed when fisherman found two conjoined grey whales on a beach inside the Ojo de Liebre lagoon near the town of Guerrero Negro, Baja Peninsula, Mexico. According to biologists the calves died shortly after birth.

 The grey whales were linked at the waist with two full heads and tail fins. To understand the rare find scientists are collecting skin, muscle and other samples.

 Considering 20,000 grey whales travel to Mexico from Alaska each year to mate and give birth, this is a very rare find, indeed!
