While diving in Bonaire a few years ago, I witnessed an impressive show of camouflage. The nine pictures below are all of the same octopus over a span of 15 minutes as we played a game of hide and seek. With its ability to change shape, skin color, and skin texture, the octopus definitely had the advantage. The most surprising moment came when the octopus assumed a fish-like shape and horizontal black stripes to cross an open patch of sand. It was a truly memorable interaction.
