Fishermen catch conjoined twin harbour porpoises

Fishermen off the coast of the Netherlands accidently caught what has been confirmed as the first case of two-headed harbour porpoise (Phocoena phocoena).

However, the fishermen who accidentally caught the deceased two-headed harbour porpoise in their beamtrawl net took some pictures of the creature and threw it back into the ocean as they feared that it would be illegitimate to keep it.

Erwin Kompanje, curator of mammals at the National History Museum Rotterdam, said parapagus dicephalus is very rare among cetaceans. Just 9 confirmed cases have been documented in whales, dolphin, and porpoises over the past two decades.

Speaking on the topic, Kompanje added, “Even normal twinning is rare; there’s no room in the womb of the mother for harboring more than one baby.”

The discovery of the first ever two-headed porpoise was detailed in the most recent edition of the Journal of the Natural History Museum Rotterdam.
