The Veined Octopus or Coconut Octopus is the only invertebrate known to use tools, and one of only two octopuses known to exhibit bipedal behaviour by “walking” on two of its legs.

Originally discovered in 1964, Amphioctopus marginatus lives in the tropical waters of the western Pacific Ocean.
The species is commonly known as Veined Octopus, named after the distinct dark brown lines that branch over the mantle and down the arms of the animal. The edges of their arms are often darkened in contrast to the white-blue suckers.

Another common name for these molluscs is Coconut Octopus, which relates to a very peculiar and interesting behaviour of the species: it carries coconut shells and clam shells across the ocean floor and uses them to build fortresses.
