The coconut octopus is found on sandy bottoms in bays or lagoons. It frequently buries itself in the sand with only its eyes sticking out.
In March 2005, researchers at the University of California, Berkeley published an article in Science in which A. marginatus was reported to have a bipedal behavior. It is one of only two octopus species known to display such behavior, the other species being Abdopus aculeatus. According to the article, this behavior was discovered in an area off Sulawesi, Indonesia, where the sandy bottom was littered with coconut shells. The bipedal motion appears to mimic a floating coconut.
Researchers from the Melbourne Museum in Australia observed the creature's use of tools for defense, and of available debris to create a defensive fortress. The discovery of this behavior, observed in North Sulawesi and Bali in Indonesia between 1998 and 2008, was published in the journal Current Biology in December 2009. The researchers filmed A. marginatus picking halved coconut shells from the sea floor and carrying them up to 20 meters (66 ft), and arranging and manipulating the shells to form a spherical hiding place. Although octopuses often use foreign objects as shelter, the sophisticated behavior of A. marginatus when they select materials, carry and reassemble them, is far more complex.[3] The researchers define a tool as "an object carried or maintained for future use", and, according to that definition, the behavior of A. marginatus is the first documented case of tool use in invertebrates.

Marine Biology is awesome.
Now naturally, the next thing to investigate is african swallow migratory patterns and behaviour in the veined octopus' habitat.
