Biological Countermeasures

Here's a nifty press release from the Scripps institute -- they've discovered a variety of marine worm which uses bioluminescent flares to dazzle predators. It's very much like the countermeasures military planes use against heat-seeking missiles. They've nicknamed the worms "green bombers" but the "bombs" don't explode. They're defensive flares, not weapons.

Marine animals seem to have anticipated other aircraft defenses by millions of years: cephalopod ink is analogous to radar-blinding "chaff." And many species use very advanced camouflage. The cephalopods, again, even have "reactive camouflage" which changes to match the surface they're hiding on. That's still on the drawing board for military applications, though apparently Japanese hipsters have already mastered it.
