Giant Pacific Octopuses are red in color but are able to change both color and texture if threatened.

Unlike the human head, an octopus head (the dorsal mantle), holds more than just the brain. It also contains the reproductive organs and digestive organs. Oddly enough, an octopus's mouth is actually a beak, very similar to a bird's. This beak is the only hard part of the octopus body and is located on the underside of the dorsal mantle, located in the middle of its arms. The size of the beak determines the size of an opening the octopus can fit through!

Each arm has two rows of suckers, the largest being close to its mouth/beak and the smallest at the tip of each arm. Each sucker can move and taste independently. They are also very strong! When aquarists interact with our Giant Pacific Octopus the powerful suction of the suckers often leaves small “octohickies” in the shape of the suckers on their forearms.

Where to Find on Campus: Eckstein Family Rivers to the Sea exhibit, National Rivers Center

Diet: Octopus has a varied diet of clams, small fishes, squid, and shrimp. 

Lifespan: A Giant Pacific Octopus can live three to five years in the wild or in captivity. They are the largest species of octopus with specimens capable of growing to a radius of 31.5 feet.

Octopuses are terminal breeders, which means they will breed toward the end of their lifespan and die shortly after. After reproduction males pass away and females will spend the rest of their lives, up to 40 days, caring for her 100,000 eggs. She will gently blow water over the eggs and guard them until she passes, ensuring the eggs are kept safe and healthy.

Did you know?

Giant Pacific Octopuses are very intelligent animals! If you happen to see what look like toys or jars in the exhibit don’t worry, aquarists use them as enrichment. Enrichment is meant to challenge our animals and bring out their natural behaviors. At the Museum & Aquarium, some of our octopus’s favorite enrichment items are plastic jars filled with food and a Mr. Potato Head toy.
