This octopus skillfully stalks and kills a squid off the coast of Hawaii. <br /><br />Footage filmed in November 2016 shows how the animal moves around the coral reef while tracking the squid, constantly changing colour.<br /><br />The cephalopod moves quickly and snares the squid with its tentacles.<br /><br />The filmer could hardly believe what he saw. <br /><br />He writes: "While recording sea turtles I found an octopus and decided to follow it for a while. <br /><br />"While recording, it changed completely white while crossing a sand patch that I thought was pretty cool. <br /><br />"Just after that, the octopus started jetting around very quickly chasing a small black squid. <br /><br />"After circling around chasing the squid, the octopus catches and engulfs the entire squid in one quick grab."<br /><br />Octopi and other cephalopods are able to change colour due to cells called Chromatophores, which can change size and colour to blend in with the animal's surrounding.
