We've posted about the Dumbo Octopus a few times before on Neatorama, but we've never seen it swim (or in this case, "dance") before:
This white octopus was filmed with a high-definition underwater video camera at 6600 feet depth 200 miles off the coast of Oregon in September 2005 as part of the VISIONS '05 expedition led by Professors John Delaney and Deborah Kelley of the University of Washington.
Little is known about the deep-sea octopuses that live in proximity to the hydrothermal vent fields associated with the underwater volcanoes of the Juan de Fuca Ridge in the Northeast Pacific Ocean.
This video features the Grimpoteuthis bathynectes species. Sometimes nicknamed the Dumbo octopus, its ears are really fins that help it move through the water.
