Pacific Day Octopus, AKA Big Blue Octopus or Cyane's Octopus, is an octopus in the family Octopodidae. It occurs in both the Pacific and Indian Oceans, from Hawaii to the eastern coast of Africa, and grows to 16 cm in mantle length with arms to at least 80 cm.

To see these guys, I usually have to get in the water a dawn, before the large crowds scare them all into hiding. First picture he is camouflaged, second he is normal, and in the third he is inking as he swims away (too close I guess with the camera?).
