Camouflage in Octopodes
Two tiny species of tropical octopus have demonstrated a remarkable disappearing trick. They adopt a two-armed “walk” that frees up their remaining six limbs to camouflage them as they slink away from trouble.
I have a fondness for security countermeasures in the natural world. As people, we try to figure out the most effective countermeasure for a given attack. Evolution works differently. A species tries different countermeasures at random, and stops at the first one that just barely works.
(I found this on BoingBoing.)
