Poor octopus walks on land. He is trying to find another crab. In search of shelter small octopus climb into empty mollusk shells, empty shells of crabs, in cans. But this one is looking for a crab to eat him. Octopuses can taste with its tentacles. On each of the 8 tentacles has more than 10 thousand taste buds that determine the edibility of an object. Almost all octopuses can change color, disguised as the environment. This happens of maximum presence in their skin cells with different pigments, which are stretched or compressed under the influence of impulses from the Central nervous system. Usual color is brown. If the octopus is frightened — he is white, if angered red. This crab is very nervous.
