Happy World Octopus Day!

Did you know? Today is (the 10th annual) World Octopus Day!

Octopuses (yes, THAT is the correct plural of octopus) are cephalopods - a class name derived from the Greek word cephalopoda, meaning "head-feet." These incredibly unique animals are characterized by their bilateral symmetry, a body shape that primarily includes a large head and set of arms or tentacles.

Out of the 800 identified living species of cephalopods, 300 of those species are octopuses! Here at the Aquarium, we have a giant Pacific octopus on exhibit. We spoke to Aquarist Katie Webster about what it's like to care for it:

Octopuses are among the most intelligent species in the animal kingdom. In total, an octopus has 500 million neurons, located in both its brain and throughout its arms. In addition to grabbing onto prey and climbing rocky underwater structures, an octopus uses its suckers to taste and sense.
