But observations of veined octopuses, known as Amphioctopus marginatus, off the coast of Indonesia surprised scientists. Not only do they use coconut shells to hide beneath, they carry the shells with them. Carrying coconut shells is no small feat for these six-inch long animals. They have to tuck the shells under their middle and gingerly tiptoe across the sea floor with their arms. When they could swim much faster and avoid being spotted by predators with water jet propulsion,why carry the shell along? Scientists believe octopuses are thinking ahead. Carrying coconuts slows them down and makes them easier to spot, but they always have somewhere to hide in the open ocean habitat where they live. Will we see octopuses building penthouses out of coconut shells any time soon? That’s highly doubtful. But the veined octopus’s behavior is intriguing and this discovery will undoubtedly encourage future research on its intelligence.
