Here is a pair of a new species of scaleworm interacting on the deep sea floor.
Why the aggression and what it means are unknown, but it is amazing to be able to watch this.
I sped the video up by 4x. The green dots (lasers) are 10 cm apart. We named this species for Prof.
Victoria Orphan from CalTech,
a good friend and amazing scientist. Victoria was running the camera in the control and took this video.
The paper naming the species is:が>>11

Peinaleopolynoe orphanae scaleworms at 3.7 km (Gulf of California) Schmidt Ocean Institute S0197.

Peinaleopolynoe means 'hungry scaleworm' as these creatures are often found living on dead carcasses like whale falls.
Peinaleopolynoe orphanae is unusual in that we found them at a hydrothermal vent.
The video was made by the dedicated team of the ROV SuBastian and R/V Falkor on dive S0197, November 18 2018.
