Rare Deep Sea Octopus Caught on Film
On the first dive of an expedition to the extreme depths of Davidson Seamount in Monterey Bay National Marine Sanctuary scientists came across this ghostly octopus.
The rarely seen Grimpoteuthis sp, commonly known as an umbrella or Dumbo octopus, was approximately 60cm (almost two feet) long.
The team aboard the research vessel Nautilus were delighted when Dumbo swam into view. One can be heard saying: 'Oh, and the world loves a Dumbo.'
As an ROV filmed the rare cephalopod, another member of the team can be heard saying: 'Yeah, he's a show-off,' and another said. 'You're going to be famous.'
There are 13 known species of Dumbo octopuses, and most of them live a depths below 3,000m (9,000 ft).
The Nautilus has been working with the Monterey Bay National Marine Sanctuary to explore an inactive, deep-sea volcanic mountain range called the Davidson Seamount. The area is about 129 km (80 miles) southwest of Monterey, California, and has been nicknamed the 'oasis of the deep,' as it hosts a wide array of deep-sea corals, sponges and other inverbrates.
Only a few days after spotting Dumbo, the Hercules ROV came across a massive octopus nesting ground, where more than a thousand deep-sea octopuses huddled in the rocks with their eggs.
