Northwest Tree Octopus The existence of the Pacific Northwest Tree Octopus is still being hotly debated on the Internet, because they just seem so plausible. These creatures supposedly begin their lives like any other octopus, as an egg in the water. In this case, the eggs are in Hood Canal, off the Puget Sound. Shortly after hatching, the young octopuses leave the waters of the canal and make their way the forests of the Olympic Peninsula. Due to a combination of the moistness of the mountain air and a special adaptation of their skin, the octopuses can survive without being in the water. Since the eye of the octopus is similar to that of a human eye, they can see well. They use their arms and suckers to climb from tree to tree, seeking prey such as insects, frogs, rodents and other small animals.
