Unlike other species of octopus, the day octopus is more active in the daytime than at night. The day octopus originally arrived at the aquarium via a direct flight from Honolulu, Hawaii, since it is native to waters there. It lives in East African waters as well. The large, almost 3-foot-long predators are short-lived. They survive just one year, on average, and breed only once.
Cephalopods, in general, don't live for very long, which is why the aquarium is cultivating cephalopods during the exhibition.
"These are all short-lived animals," Monterey Bay Aquarium special exhibits coordinator Jennifer Dreyer said. "Many are species that have never been exhibited for very long by any of our colleagues, or raised through their entire lifecycle. This is definitely a first for any aquarium."
