Fishermen from the Netherlands caught a dolphin with two heads
Dutch fishermen accidentally caught in the North sea two-headed Dolphin and gave it to the photography scholar.
«Anatomy of cetaceans is radically different from the device body other mammals due to the fact that they are adapted to life at sea. Much of what separates us from the whales and dolphins remains unknown. Therefore, the discovery of a single case of diceglie among cetaceans in addition to the nine already studied gives us a lot of new knowledge,» said Erwin Companie (Erwin Kompanje) from the National historical Museum of Rotterdam (Netherlands).
In late may, the fisherman Hank Tanis and his companions were fishing in the North sea approximately 30 kilometres off the coast of the Netherlands. Pulling the network out of the sea, the Dutch have discovered in it no fish, and baby sea pig with two heads (Phocoena phocoena).
This Dolphin is similar to the well known Siamese twins had two heads, three eyes, and one body with a «normal» set of limbs and organs. The fishermen were frightened findings and threw it into the sea, believing that such a «catch» illegal from the point of view of EU law and the Netherlands.
But before that, Tanis and his companions took a few dozen photos of the Siamese Dolphin, and subsequently handed them over to the scientists. A description of the findings and photos were published this week in the journal DEINSEA.
As noted Companie scared it is a wonder – Dolphin, judging by the photos its fragile tail and dorsal fin, died almost immediately after exiting the womb. Fishermen shouldn’t be throwing it back – in the words of oceanographer, a two-headed porpoises had never met, and the study of the body of such an animal would help to understand why it died and what kind of mutation caused the appearance of a second head.
The discovery is also interesting for the reason that these disorders rarely occur among cetaceans. As a rule, their females give birth to only one cub, and the mechanism of occurrence of the second of a zygote in their womb, somehow merging with the first, is still a mystery to scientists. Companie and other researchers hope to reveal it as the discovery of new cases.
