Giant Pacific octopuses are the largest species of octopus in the world, reaching an average weight of 132 pounds (60 kilograms), though they only live an average of four to five years. While generally solitary animals, giant Pacific octopuses are generally calm, intelligent animals that have been known to use tools, navigate using landmarks, and even use their adept vision to learn through observation.
The thousands of suckers on their arms contain sensitive chemoreceptors that provide the giant Pacific octopus with a sharp sense of touch and taste. As a result, octopuses have been known to solve a number of puzzles presented to them, including opening child-proof bottles.
The International Union for Conservation of Nature (IUCN) has listed the giant Pacific octopus population as Least Concern due to a wide geographic range and large number of eggs laid. Least Concern populations are those that are unlikely to become extinct in the near future.
