The first known sighting of conjoined twin porpoises have been reported in the Netherlands. The animals were dead when the fishers caught them.  

They threw them back into the water because they feared keeping the dead animals was illegal. They did, however, take a few photographs to document their existence.


 

The porpoises were male babies, not-yet-firm dorsal fin, small hairs on their upper jaws and an open umbilicus from where they had been attached to their mother.

They had fully formed heads which were connected to a single body with the usual two pectoral fins. They were about 2 feet long and weighed about 13 pounds.  

This report of conjoined twin porpoises is the 10th known instance of symmetrical conjoined twins among cetaceans, the scientific name for the marine animal group including whales, dolphins and porpoises. Such twinning also has been found among baleen whales and toothed whales. 

Scientists believe that symmetrical conjoined twins are the result of either embryonic cells that had been separated fusing together or the incomplete separation of cells from a fertilized ovum.
