I recently visited a new Giant Pacific Octopus at the Akron Zoo in Ohio. Weighing in at approx. 18 lbs, the male or female (not known but I'll say 'he') was sleeping in his exhibit, up against the back wall but on full display. It was late afternoon and he was a moderate pink color. I was watching him for about five minutes when all of a sudden he started to twitch and turned a deep red. He twitched for a few more moments and then stopped and his color lightened and eventually ended with a marbled pattern. Certainly octopuses have the intelligence to dream, correct? But I don't recall ever reading anything about that topic. Any thoughts?
