Fishermen in the North Sea near the Nethelands caught the first two-headed porpoises ever documented. The trawler crew found the animal already dead in its nets. From Deinsea, the journal of the Natural History Museum Rotterdam:
"The crew of the fishing vessel thought it would be illegal to keep the dead porpoise and they threw the specimen back into the sea. Fortunately, first a series of photographs was taken. The specimen, however, is lost for science and natural history."
