An octopus changes its colour very quickly even faster than a chamelion. Its suckers gives it sensing information about its surroundings and enables it to hide from its predators and to prey. But animals like seals which can see only black and white colours can spot them and then the whole group of seals attack the octopus. In such case an octopus can prevent its death by using its powerful suckers to stick to the rocks or throw a shower of blackish fluid, the same material which is found in human hair and nails to give it some time to escape. Octopus are self species eater and can prey upon any small octopus.
