Scientists have observed chimps using tools to get food, but scientists were surprised to see octopuses using tools--and not for food-gathering, either! As seen in the video above, octopuses near Indonesia were seen using the coconut shells as mobile shelters. Sometimes they would even fit two halves of a coconut together to make a hiding place. Even though the octopuses moved more slowly carrying coconut shells, they always have a place to hide from predators if they bring them along.

The sight of the octopuses moving across the ocean floor carrying the coconut shells wasn't just surprising. It was also very funny! "It was hard not to laugh underwater and flood your [scuba] mask," said biologist Mark Norman.
