October 8: World Octopus Day
October 8 is World Octopus Day
Octopus facts:
They are the first invertebrates to be seen using tools, such as using coconut shells to hide from potential predators and using rocks and jets of water in a way that could be classified as tool use.
Common octopuses will collect crustacean shells and other objects to construct fortresses, or “gardens,” around their lairs. Other octopuses carry shells for protection.
