This is the first time that we have seen invertebrates using tools. Octupuses have been filmed using these tools for their protection. This is
remarkable behaviour. There has to be some cognitive intelligence in Octopus because it not only uses the tool to hide from threats, it also carries
it away for future use.

Octopuses have been observed carrying coconut shells in what researchers claim is the first recorded example of tool use in invertebrates.
veined octopuses, Amphioctopus marginatus, have been filmed picking up coconut halves from the seabed to use as hiding places when they feel
behaviour qualifies as tool use for a number of reasons. First, the shells are not permanent homes like those occupied by hermit crabs, but are
carried around for future use.
