Umbrella of tentacles
The graceful dumbo octopus twirled and opened up its umbrella of tentacles, revealing eight rows of suckers.
The team used scaling lasers on the ROV to estimate that this particular deep-sea ghost was just under 2 feet (60 cm) long, which is a little larger than most dumbo octopuses.
