The carcass, found on Wednesday, is only the 14th pygmy whale
to be found on the UK's shores, out of about 16,000 dolphins, porpoises and whales analysed by the CSI programme in its 29-year history.

The discovery may help to explain the pygmy whale's unique appearance; the comparatively small whale (adult pygmy whales typically only grow to about 21 feet long) has a distinct, downturned snout that looks almost like a permanently etched in frown.
However, the new study, which examined pygmy whale fossil fragments and skull bones and contrasted them against those of other ancient cetaceans, found that the pygmy whale more closely resembled a group of whales called cetotheres, thought to have vanished over two million years ago, said Felix Marx, a paleontologist at New Zealand's University of Otago.
"It's the last survivor of quite an ancient lineage that until now no one thought was around." Yet despite the interesting finding, Marx said that researchers were unable to find any evidence of how the pygmy whale had evolved.
Wildlife rangers and volunteers used pontoons to float the killer pygmy whales
-- part of a group of 12 found beached in the country's far north on Sunday -- and take them about 400 meters (437 yards) offshore.
In separate incidents, 12 pygmy whales
and a sperm whale also
In separate incidents, 12 pygmy whales and a sperm whale also beached in New Zealand over the weekend.
Also over the weekend, 12 pygmy whales were found stranded at the northern tip of North Island.
Dolphins, manatees, sea turtles, pygmy whales
and even a whale shark washed ashore.
