Octopus (Pulpo común)

Here we have a nice shot of an octopus as it swims.  The yellow tube below its eye is what allows it to have such great acceleration because that´s what it uses to pump water out, thus creating a type of "jet propulsion".  And it´s coloration is also quite noticeable, since it can change color and texture at will.  A remarkable animal, which tastes superb if cooked properly!
