Dutch fishermen in the North Sea have found an unusual two-headed harbor porpoise. This was a very rare creature that shared a single body. This two-headed porpoise was a set of conjoined newborn twins. Unfortunately, the small mammal had already lost his life when the fishermen took it out from the chilly water. Fishermen feared to keep the dead porpoise, as it would be illegal. So they have decided to throw this rare creature back to sea. But before throwing it, they have taken some snaps of this odd looking two-headed creature.

These snaps were sent to Dr. Erwin Kompanje of the Natural History Museum. Kompanje has been researching on dolphins, porpoises and whales for more than twenty years. He has never seen such odd looking creature before this.

Kompanje told the media that the two-headed creature was very rare and magical. Twins are very rare in cetaceans.

He further added that this was the rarest case ever as he never found conjoined twins. He says that there is around 700,000 harbor porpoise in the world, half of them are living in the North Sea. It is the first incident on record.

He told that there had been nine other conjoined twins in a cetacean species of whales and dolphins. In 2014 a two-headed conjoined set of dolphins was found in western Turkey. These dolphins were also died, just like two-headed porpoise when they were taken out.

Kompanje further adds that dolphins know how to swim immediately after birth. However, due to their complex structure, these conjoined twins were unable to swim.

The scientists have further studied these snaps and found an umbilical opening of the two-headed porpoise. It suggested that the twins died just after the birth.

Few scientists lamented that this rare creature was thrown back to sea. It could have given some unique information about its anatomy.

Kompanje said that we are very curious to know about the anatomy of conjoined twins. Cetaceans have got highly developed spinal musculature since they use it for their movement.
