Story Behind the Shot – Coconut Octopus

I am a big fan of octopus, I would willingly spend an hour with a curious octopus watching it go about its daily life, combing its environment looking for food and avoiding predators. The species of octopus doesn’t matter; they all seem to have an innate curiosity of their surroundings and will often interact with a diver who moves slowly and carefully.

Coconut octopus in Puri Jati, Bali, Indonesia

One of my favourite octopus encounters was with this coconut octopus during a dive at Puri Jati (PJs) in north Bali, Indonesia. Coconut or veined octopuses, Amphioctopus marginatus, have recently been designated as the first invertebrate able to use tools, elevating their status as an intelligent animal. On this dive, I encountered this guy in less than 5 metres of water and was able to spend a long time watching and photographing his/her daily life. The first thing that stands out in the photograph is that the octopus is obviously using the coconut shell as a home (hence the name) but that the “roof” of the house is a bright pink plastic cap! This photograph pretty much sums up the intelligence of these animals and lends credence to the idea that they can use tools. Not finding a suitable shell to use a “roof” to close up the shell when threatened, this octopus was able to substitute the next best thing it could find. Thinking I would help out this little guy and find it a clam shell to use instead of a piece of bright pink plastic, I found a big clam shell and brought it over, but when I set it beside the octopus it showed no interest whatsoever!  He/she was more than happy with its bright pink roof and just picked up its shell and trundled away!
