Ganked from the journal page of frogsbreath here : Beautiful video of a largely-unknown octopus species, captured serendipitously by a maintenance ROV.

It resembles an octopus around the head end, but it's trailing a tremendous long veil patterned with leaves and eyespots. At the end of the video, part of the veil is dropped, apparently as a defense mechanism, and the arms flare out more of the veil like wings and shade its color to red in a warning display.

According to tolweb, the young collect the stinging tentacles of the man o' war and wear them for further defense.

There are more things in heav'n and earth...
