What a day for a day octopus

Day Octopus

Day Octopus on the moveThe trick to spotting an octopus is to see it in motion. I’ve seen one or two when they’ve been stationary, but only by accident, watching something else and realizing that there was something slightly odd about that ‘rock’ next to it.

When I do see an octopus, one of the first things I tend to notice is the siphon and the outdated facial recognition software that is my brain thinks, ‘that’s an eye.’ Except it isn’t.

In the top photo, the eyes of this day octopus can be seen at the highest point of the view. The siphon, orange on the outside and white inside, is below and a little to the right. The siphon, also known as the funnel or hyponome, is used for respiration, waste disposal, and discharging ink. It’s also used for locomotion. Water is taken in through the aperture around the siphon and then expelled out of the siphon, propelling the octopus in the opposite direction.

The bottom photo shows the octopus changing its coloration. They can change their color and texture to blend in with their surroundings. The middle photo shows the octopus saying ‘I’ve had enough of this. Arrivederci.’

        I can see why. They are so different. Years back when exploring rock pools on a wildish bit of coast, I jumped over a small rock pool, and a previously unnoticed octopus extended a tentacle high out of the water as if trying to catch my foot. Perhaps a reflex on its part? I was mighty surprised.
