Some great links on the biology, cognition, and behavior of octopus, cuttlefish, and other cephalopods, including the incredible morphology of their arms and skin, and attendant development of their highly distributed neurological system (same number of neurons as a cat, but 2/3 distributed throughout the arms) and associated behavior (mimicry, camouflage, mesmerization, and other nomadic/”soft” tactics).

Great video of octopus and the beer bottle – squeezing and adaptive coloration. VERY USEFUL
Overview of octopus morphology and intelligence. USEFUL, esp. at 3:40
Great overview of octopus neurology.
