It appears that Taningia danae, a deep-sea squid, uses "bright flashes to disorientate potential victims", much like Ts and CTs use flashbangs in order to blind, confuse, and incapacitate their opponents in CS.
Check out the story here, and don't miss the video.
Fire in the hole! Me ga mienai!
Ah, sometimes it's fun to revel in one's own nerdiness.
On a side note, I am willing to bet that T. Danae tastes nasty. I know that the smaller, bioluminescent hotaru ika (firefly squid), considered a delicacy in Japan, doesn't rate among my favorite calamari dishes.
