Weird deep sea creatures

(Video link) Here's a weird sea creature caught on video by a remotely operated undersea vehicle.

(Video link) This deep-sea squid was videotaped by one of Shell Oil's deep sea robotic rovers in the Perdido Area of Alaminos Canyon, at 7800 ft. depth.

(Video link) Then there's the "vampire squid" (Vampyroteuthis infernalis), a living fossil which can turn itself inside out to avoid predators. 

(Video link) This video shows a variety of deep ocean creatures with some remarkable uses of light for attracting or confusing prey. Most all of these are new to science, as 95% of the deep ocean is yet to be explored.
