A juvenile giant Pacific octopus (Enteroctopus dofleini) was sitting out on a ledge as I kicked along the deep wall at Madrona Point on Vancouver Island. This little fellow was great to watch as its skin folds extended to allow this animal to blend in with the surroundings. This one is on the small side, but the average size of a mature giant Pacific octopus is about 90 pounds (40.8 kg). Many have been discovered weighing 150 pounds (68.0 kg)! The giant Pacific octopus has a range that includes Japan, Siberia, and northern Alaska to northern Mexico.
