Some of these species of fish remind me of ex-girlfriends :biggrin2:

Thanks for sharing! Awesome video.

Regarding bio-luminescence as defense mechanism in deep-sea cephalopods:

"The production of luminous clouds is common among
other deep-living pelagic invertebrates but rare in cephalopods.
Anecdotal evidence for the production of luminous
clouds by squids was summarized by Young et al. (1979),
who suggested that renal fluid might be the luminous substrate.
The only well-documented case is the sepiolid Heteroteuthis,
which ejects a cloud of luminous particles when
it is disturbed, presumably as a distraction to predators
(Herring, 1977). The ejecta is produced by glands within the
mantle that contain dense populations of light-producing
bacteria, which are combined with ink and mucus during
release through the siphon (Herring, 1988, 2002). The
glands themselves emit light and have complex internal
reflectors, which suggests that they have multiple uses (Herring,
1988). Structurally and operationally, the release of
luminous fluids appears to be a completely different process
in Vampyroteuthis than it is in Heteroteuthis."

There's a relevant event this June in NYC:

http://www.worldsciencefestival.com/illuminating-the-abyss

Saturday, June 5, 2010, 4:30 PM - 6:00 PM
The Paley Center for Media

"The oceans remain a realm of mystery, with an astonishing 95% still unmapped, but their secrets are starting to be revealed. Journey into the deep to explore exciting discoveries like sea sponges with cancer-fighting potential and underwater mountain ranges that may hold the clue to life’s origin. Rare footage of pioneer Jacques Cousteau will take us back to the early days of passionate ocean exploration; the premiere of "behind-the-scenes” footage from Jacques Perrin's new film Oceans will inspire with a vision of what lies ahead."
