Protecting Octopuses’ Coastal Homes
There are many ways humans can share healthy coastal areas with species like the giant Pacific octopus. One way is to establish underwater reserves or Marine Protected Areas (MPAs), like the Olympic Coast National Marine Sanctuary. This 2,400 square mile sanctuary in Washington State was established to preserve one of the most productive, healthy ecosystems in North America.
Where is the Octopus?
Despite its size, visitors sometimes have difficulty finding the octopus when they first approach the Olympic Coast exhibit. This is because the octopus is a master of camouflage and often prefers to curl up in a corner during the day. The tank’s dim lighting and nooks and crannies create an ideal atmosphere for the octopus.
