I was trying to find an octopus on my every diving occasion. Finally I made it today. I went for a short dive before the breakfast, first time this year and met 2 or three octopuses.
First, I've noticed one slowly getting out of his hideout.

He was changing colors, and was doing all the stuff octopus is supposed to do.

First red.
It just takes a fraction of a second to turn to a stone.

Just few seconds before Julia had sprinted to me, another octopus approached this one and they fled to coral fields together

And once again, they changed color to blue.
