Deep - ocean researchers led by Robert Ballard ( well known for his 1985 discovery of the Titanic wreckage ) have caught a rare , extended look at an uncharacteristically jumbo dumbo octopus , with the aid of a remotely operate fomite ( ROV ) in the unlit deepness of the Caribbean sea .
“ You have sex , bunch of times you ’ll just see a glimpse of an octopus , or one will go by , ” one of Ballard ’s colleagues can be heard saying in the video above . “ To be able to just focus on it like this and stay with it is just exceptional . ”
Here ’s SciAm ’s Katherine Harmon Courage – an octopus expert , herself – on what it is we ’re seeing here :

The Dumbo isa cirrate octopus , a character of deep - ocean octopus that has thin strands ( cerri ) that extend from the bottom side of its arms along with the suckers . Its substantial heavy web is responsible for this genus ’s other nickname , the umbrella octopus . There are more than a XII different metal money in the genus . They dwell in many places around the globe and can survive at depths up to ( or down to ) several thousand meters below sea level .
The squad aboard the Nautilus uses red laser loony toons to estimate the sizing of objects it ensure in the ROV ’s video provender . And this Dumbo proved to be a self-aggrandizing one . It was forecast to be a humongous m long — a good five time the size of it of an average Dumbo .
Ballard and his team have spent the summertime aboard the research vessel The Nautilus on an expedition with the Corps of Exploration . you may follow the team on its adventures , live , through the jaunt ’s website .
