Octopus (pulpo común; octopus vulgaris)

Here´s a nice photo of an octopus in its den.  It was sitting there on its front porch watching the world go by when we came by.  As you can see, it "circled its wagons" in a defensive posture.  Look at the size of its suckers!  Keep in mind that an octopus can exert incredible strength, much more than a grown man, as many of us can attest to.  Some will play with you, others won´t.  This one was just enjoying a nice morning on the bottom, so we took a few photos and went on our way.
