Two-headed porpoise pulled from the ocean in the North Sea

June 16, 2017 by Bob Yirka report

A newly born two-headed porpoise has been documented by a group of Dutch fishermen and studied by a team of researchers from several institutions in the Netherlands. In their paper published in Deinsea—Online Journal of the Natural History Museum Rotterdam, the researchers report how the fishermen caught the porpoise, photographed it and then threw it back into the ocean.

Reports of conjoined twins in cetaceans (a family that includes whales, porpoises and dolphins) are rare, quite naturally because they occur in the open sea—it is also likely that most would die shortly after birth, like the specimen found by the . In this case, it appears the was born without the ability to swim.

The fishermen knew the porpoise was a rare find, but because they were subject to rules preventing them from keeping caught mammals, they were compelled to throw it back into the sea—but not before taking multiple photographs, which they sent to the team at Deinsea.

In studying the photographs taken by the fishermen, the researchers found signs that it had been born very recently—the were limp and the umbilical opening was still open—also, the tail had not stiffened, which meant it could not swim. Additionally, both of the heads still had rostrum hair, which disappears in healthy porpoises shortly after birth. The research team reports also that the porpoise was male, and that it had two heads that were fully formed. It also had individual pectoral fins, but just one body. They suggest it is likely the porpoise was symmetrically conjoined, which happens when two embryos fuse into one. In other cases, a single embryo does not split, preventing the development of separate twins.

Though there have been nine previous cases of known conjoined sightings in cetaceans, this is the first for a porpoise. Researchers believe that twins, conjoined or otherwise, are rare in porpoises because porpoise calves in utero are too large. The development of conjoined twins would normally kill the mother, though it is not known if that was the case for the one found in the North Sea.

Fukushima. Tip of the iceberg.

To point: Fukushima is still ongoing. It has not been slowed. Humanity making a mess of the environment and killing off the oceans was bad enough.

Fukushima is moving that rolling nightmare forward by more than a magnitude -in rate and speed of downturn.

Fukushima does not really make the news anymore, but it is still ongoing at the same level it was at the start.

@KBK, you are correct my friend.

Saw an infrared satellite pic of the before and after spread of radiation from Japan.

California is now getting splashed by this killer water.

So maybe I will grow two heads and be twice as smart! ;-)

The first thing I thought was also Fukushima. I live in Hawaii, and supposedly it's radiation has come into our waters. You would think that by now, there would have been several examples of such deformities off coastal Japan, but nobody is seeing it.

This is a one off I am sure, and has nothing to do with the environment. freakish two headed turtles, snakes, cows, sheep and similar have happened over and over again, and there has never been a link to them being that way due to exposure to toxins or man-made waste.

Considering that this one was found in the Atlantic North Sea I do not think Fukushima could be at all the problem here. Certain various chemicals and the Atlantic has it's own radiation problems, but you cannot just go blaming things on Fukushima when this is the entire other side of the world from it.

"The fishermen knew the porpoise was a rare find, but because they were subject to rules preventing them from keeping caught mammals, they were compelled to throw it back into the sea—but not before taking multiple photographs, which they sent to the team at Deinsea..."

That could be total bull. Considering that the animal was dead, they could have kept it for scientific study... Who is to say they didn't and this article is just BS'g to cover up something in the Atlantic?
