The giant octopus is one of the largest invertebrates. Its arms can reach up to 30 ft (9 m). The eight legs of the octopus are covered with sensitive suckers that can distinguish objects.
The octopus can change color to camouflage itself and to reflect its mood. Red indicates that it is annoyed and pale indicates that it is stressed. The octopus changes colors by expanding or contracting the cells that contain the pigment.
