World Octopus Day celebrates those 8-armed cephalopods that live in the sea. Most of us probably don’t think about octopuses in our daily lives, but they’re definitely creatures that deserve our attention for at least one day of the year. Octopuses are remarkably intelligent and adaptable. They’ve been known to escape from aquariums and they are one of the few animals besides humans that use tools. They are also older than most creatures currently alive today. Some octopus fossils have been found that date back to a time before even dinosaurs walked the Earth. Celebrate this holiday by visiting a local aquarium to see the octopuses up close, or simply educating yourself and others about just how amazing octopuses are.
