There is much we do not yet know about the deep parts of our oceans. What you can see in this video is a very rare sight.
Researchers have now been successful in filming a seven-armed octopus called ‘Haliphron atlanticus’. It can grow up to four meters long and weigh almost 75 kilos. But because they stay at great depths, they are difficult to study, and researchers still know very little about it. Watch it feast on an egg-yolk jellyfish called ‘Phacellophora camschatica’.
