This curious giant Pacific octopus (Enteroctopus dofleini) had its eye on me as I approached to take a closer look. These animals are fascinating with their eight strong arms, loads of suction cups, slow graceful movements, and inquisitive nature. It has been determined that an octopus is very intelligent, even comparable to a dog. This large octopus was nestled into a crevice seventy feet deep on wall at Madrona Point, Vancouver Island. 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 is the largest octopus in the world and has a range that includes Japan, Siberia, and northern Alaska to northern Mexico.
