An unidentified purple octopus (pictured) is one of 11 potentially new species found this month during a deep-sea expedition off Canada's Atlantic coast, scientists say.

Still at sea, a team of Canadian and Spanish researchers is using a remotely operated vehicle called ROPOS for dives off Newfoundland with a maximum depth of about 9,800 feet (3,000 meters).
The 20-day expedition aims to uncover relationships between cold-water coral and other bottom-dwelling creatures in a pristine yet "alien" environment, according to the researchers' blog.
"It's been really spectacular," Ellen Kenchington, research scientist with the Fisheries Department of Canada—one of the organizations involved in the project—told Canada's CTV News website.
"It's really changing our perception of the diversity that's out there. ... We're seeing new species in deeper waters."
