Bizarre pink worm in deep ocean has links to humans
A strange pink worm has been discovered 12,000 feet (3,658 metres) below the waves and may be one of our earliest ancestors.
It is among the four bright fuchsia flatworm-like animals found near hydrothermal vents, as well as on a whale carcass off the coast of California. This new species is the four-inch-long Xenoturbella churro — named for its resemblance to churros, a popular Spanish fried pastry. The experts used DNA analysis to identify this flatworm-like animal as the most primitive still-existing member of the group of animals that includes man, called deuterostomes.
The animal kingdom is divided into three main groups. The first, the ecdysozoa, includes insects and crustaceans. The trochozoa comprises the molluscs and earthworms. We belong to the last group, the deuterostomes, and strangely Xenoturbella also belong to this group.
The largest of the new species, Xenoturbella monstrosa, was found in Monterey Bay, off the coast of California and the Gulf of California, and measured eight inches in length while the smallest was only one inch long.
