A creature with a musical name presents a spectacular light show to the cameras of the Monterey Bay Aquarium Research Institute‘s remotely operated vehicle. This ctenophore seems to be exhibiting bioluminescence, but what the “lights” actually represent is reflection or refraction of the photoflood lights from rhythmically beating cilia. The deep red color is a survival adaptation, helping to mask the bioluminescence of creatures it ingests, so that it does not itself become visible to other predators.
It has been suggested that comb jellies such as the ctenophores are ancestors of all life on earth.

Remember the post about Micropinna microstoma, the fish with a transparent head? In that post, Neatorama reader sniggitysnags told us about the existence of the video clip by Monterey Bay Aquarium Research Institute researchers:
MBARI researchers Bruce Robison and Kim Reisenbichler used video taken by unmanned, undersea robots called remotely operated vehicles (ROVs) to study barreleye fish in the deep waters just offshore of Central California. At depths of 600 to 800 meters (2,000 to 2,600 feet) below the surface, the ROV cameras typically showed these fish hanging motionless in the water, their eyes glowing a vivid green in the ROV’s bright lights. The ROV video also revealed a previously undescribed feature of these fish–its eyes are surrounded by a transparent, fluid-filled shield that covers the top of the fish’s head.
This animal is so awesome that we just have to put it on Neatorama’s front page again: Hit play or go to Link [YouTube] – Thanks sniggitysnags!
