Revealed: The bizarre creatures living at the bottom of the Arctic and Antarctic seas
| Mail Online: "At least 235 types of cold-loving creatures have been discovered thriving at the bottom of the Arctic and Antarctic seas, puzzling scientists about how they got to both ends of the earth.
Until now, the warm tropics have been seen as a barrier keeping polar bears in the Arctic separate from penguins in the Antarctic. Only a few creatures have been known� to live in both polar regions, such as long-migrating grey whales or Arctic terns.
'At least 235 species live in both polar seas despite an 11,000-km (6,835 miles) distance in between,' a decade-long international project to map the world's oceans , Census of Marine Life, has found."
