Inside the mind of the octopus
J Thoendell stashed this in Science
As we gazed into each other’s eyes, Athena encircled my arms with hers, latching on with first dozens, then hundreds of her sensitive, dexterous suckers. Each arm has more than two hundred of them. The famous naturalist and explorer William Beebe found the touch of the octopus repulsive. “I have always a struggle before I can make my hands do their duty and seize a tentacle,” he confessed. But to me, Athena’s suckers felt like an alien’s kiss—at once a probe and a caress. Although an octopus can taste with all of its skin, in the suckers both taste and touch are exquisitely developed. Athena was tasting me and feeling me at once, knowing my skin, and possibly the blood and bone beneath, in a way I could never fathom.
When I stroked her soft head with my fingertips, she changed color beneath my touch, her ruby-flecked skin going white and smooth. This, I learned, is a sign of a relaxed octopus. An agitated giant Pacific octopus turns red, its skin gets pimply, and it erects two papillae over the eyes, which some divers say look like horns. One name for the species is “devil fish.” With sharp, parrotlike beaks, octopuses can bite, and most have neurotoxic, flesh-dissolving venom. The pressure from an octopus’s suckers can tear flesh (one scientist calculated that to break the hold of the suckers of the much smaller common octopus would require a quarter ton of force). One volunteer who interacted with an octopus left the aquarium with arms covered in red hickeys.
Occasionally an octopus takes a dislike to someone. One of Athena’s predecessors at the aquarium, Truman, felt this way about a female volunteer. Using his funnel, the siphon near the side of the head used to jet through the sea, Truman would shoot a soaking stream of salt water at this young woman whenever he got a chance. Later, she quit her volunteer position for college. But when she returned to visit several months later, Truman, who hadn’t squirted anyone in the meanwhile, took one look at her and instantly soaked her again.
