chickweedThe coconut octopus is found in tropical waters of the western Pacific. It feeds on shrimp, crabs, and clams, and displays unusual behavior including bipedal walking and tool use; it gathers coconut shells and seashells and uses them for shelter.
It displays a color pattern with dark ramified lines similar to veins, normally with a yellow siphon. The arms are usually darker, with contrasting white suckers.
