You’ve probably heard that octopuses are smart… but exactly how smart? Well, the Amphioctopus marginatus, also known as the coconut octopus, has found a clever way to use portable protection by carrying around a coconut and closing itself inside.
According to Wikipedia, “researchers from the Melbourne Museum in Australia claimed the coconut octopus uses tools for concealment and defense by gathering available debris to create a defensive fortress. This behavior was observed in individuals in Bali and North Sulawesi in Indonesia. The researchers filmed the octopus collecting coconut half-shells discarded by humans from the sea floor. They were then carried up to 20 meters (66 ft) and arranged around the body of the octopus to form a spherical hiding place similar to a clam-shell.”
