Videos of bizarre life around deep-sea gas vents

From the associated post "Voyage reveals bizarre life around deep-sea gas seeps (Video)":

"An international team led by scientists from the United States and New Zealand have observed, for the first time, the bizarre deep-sea communities living around methane seeps off New Zealand's east coast.":

A recent post on extremophile life "Bacteria using radiated water for food live two miles down":

Researchers have discovered an isolated, self-sustaining, bacterial community living under extreme conditions almost two miles deep beneath the surface in a South African gold mine. It is the first microbial community demonstrated to be exclusively dependent on geologically produced sulfur and hydrogen and one of the few ecosystems found on Earth that does not depend on energy from the Sun in any way. The discovery, appearing in the October 20 issue of the journal Science, raises the possibility that similar bacteria could live beneath the surface of other worlds, such as Mars or Jupiter's moon Europa.

"These bacteria are truly unique, in the purest sense of the word," said lead author Li-Hung Lin (homepage), now at National Taiwan University, who performed many of the analyses as a doctoral student at Princeton and as a postdoctoral researcher at the Carnegie Institution's Geophysical Laboratory.
