Unusually Large Dumbo Octopus Sighting
E/V Nautilus is exploring the ocean studying biology, geology, archeology, and more. WATCH live video from the ocean floor.

Cirrate, or finned, octopods (which are also known as “dumbo” octopods because the fins on the sides of their bodies make them look like the flying elephant in the Disney cartoon) can be divided based on their behavior. One group spends a lot of time sitting on the bottom but sometimes gets up and swims by a combination of fin flapping and jellyfish-like pulses of the arms and web. Members of the other group seem to spend all of their time up in the water and not on the bottom.
Tentacles in Darkness: New Life found off Patagonia
"We spend a lot of time investigating outer space, but we still need to understand our oceans," scientist and Pew marine fellow Vreni Häussermann says.
She’s discovered a region in the Pacific Ocean where “a huge amount of tentacles reach out of the dark” and where deep ocean life thrives at the surface. See what it’s like in the cold Chilean fjords in this colorful new video short, part of a new series from Pew, One Minute Dive.
Patagonia is Chile’s most famous region, but its 8,000 kilometers (almost 5,000 miles) of coastline remain largely unexplored. When scientist Vreni Häussermann began diving into the fjords, she soon discovered that the frigid water teems with life, another world, right here on Earth.
Häussermann directs the Huinay Scientific Field Station in Chile, where she organizes and leads scuba expeditions to remote areas of the Chilean fjord region. Her work has led to the discovery of dozens of bottom-dwelling species and marine communities.
But beyond the excitement they generate, her discoveries in the Patagonian fjords are adding to our understanding of our oceans and illustrating the important connections between land and sea.

Humans have driven to extinction four marine mammal species in modern times: Steller´s sea cow in 1768, the Caribbean monk seal in 1952, the Japanese sea lion in 1970 and the baiji or Chinese river dolphin in 2006. As you read this, we are on the brink of losing the fifth.
The vaquita (Spanish for “little cow”), a small porpoise that lives only in the uppermost Gulf of California, Mexico, is the most endangered of the 128 marine mammals alive today. The vaquita, which some say looks endearing with its unique facial markings, is the smallest of all whales, dolphins and porpoises.
The only way to prevent its extinction is if the Mexican, U.S. and Chinese governments take immediate and coordinated action.
