Giant Pacific octopus

What has three hearts, about 1,600 suckers and is using eight arms to wave goodbye to Cephalopod Week? If you’ve been following along, you know we’re talking about the giant Pacific octopus! We hope this latest week of at-home engagement has been fun, educational and inspirational.

And we couldn’t close out the week without squeezing in a few details about the annual giant Pacific octopus survey in Puget Sound, which we launched in 2000. While there’s no way to know how many octopuses are living in our local waters, these annual surveys provide a good sense of population trends. See below for a trivia question based on the 2018 survey!
