Octopus is a force to be reckoned with

Camo: "Two deep-ocean species of cephalopod, an octopus and a squid, can go from transparent to opaque in the blink of an eye, a new study finds." (active camouflage)

Smarts: despite a walnut size brain (distributed through its arms and head), the octopus displays tool use and play and some basic language skills.

Technology: manipulates stones and shells for tools.
