GIANT PACIFIC OCTOPUS

Latin name: Enteroctopus dofleini

Giant Pacific Octopus
Location: Large central tank near the main Visitor Center entrance

The giant Pacific octopus is a common resident off Oregon's coast. It is a predator that dines on crab, shrimp, crustaceans, shellfish, smaller octopuses, and fish, and can chase its prey by "running" or jetting after prey animals and capturing them with its arms. Then the octopus uses its parrot-like beak, located at the center of its soft body, to deliver a venom that paralyses and liquefies the meat of animals. An octopus can spend several hours feeding on one crab and will usually remain dormant until finished.

The octopus is known as the most intelligent invertebrate and exhibits clear signs of both curiosity and memory. Octopuses have been observed climbing out of one tank to grab nearby food in another. An octopus can unscrew jars, uncork champagne bottles, and mimic the behavior of a neighboring octopus.

Octopuses live in rocky dens and will defend their territory until it is time to mate. Females lay 50,000 to 70,000 eggs and will care for them until they hatch. A lot of energy goes into reproduction; both adults will die shortly after the hatch.

The territorial nature of this animal makes it nearly impossible to keep more than one in a single tank.

Predators include lingcod, dogfish, seals, sea otters - and humans.

You may be able to watch staff members feed our octopus, and learn more about its habits, during your visit. Check the feeding schedule.

Our Web visitors can watch our resident octopus, too, via the live, streaming OctoCam!
All you need is a Web browser equipped with Flash, and a good Internet connection. You can even tune in at feeding time and listen in as our aquarists and volunteers talk about octopus biology and behavior.
