The Giant Pacific Octopus is one of the most impressive marine animals due to its strange shape, lifestyle, and feeding methods. Follow this article to learn more about it on TekeTrek.
Physical Characteristics
- The Giant Pacific Octopus belongs to the Animalia kingdom, Mollusca phylum, and Cephalopoda class. It is the largest species of octopus. Typically, the Giant Pacific Octopus is reddish pink with a delicate vein-like pattern when seen up close, and the pink fades to white on the underside of the arms.
- Anatomy: Like all octopuses, the Giant Pacific Octopus is a mollusk and an invertebrate without bones, with a soft body. Its shell has been reduced to two small plates that support the head muscles, in addition to a strong beak resembling a parrot’s.
- Arms and Senses: The Giant Pacific Octopus has eight arms covered with suction cups, providing a strong grip, as well as taste and smell senses. The arms can stretch from 2 to 4 meters from tip to tip.
- Hearts and Brains: Besides eight arms, the octopus also has three hearts and nine brains. Two of the hearts pump blood to the gills, while the third circulates blood to the rest of the body. The octopus uses one central brain to control its nervous system and a small brain in each arm to control movement. Octopuses, including the Giant Pacific Octopus, have blue blood due to a copper-rich protein called hemocyanin in their bloodstream, which is effective in transporting oxygen in cold ocean environments.
Giant Pacific octopus habitat
The Giant Pacific Octopus can be found throughout the Pacific Ocean, from Korea and Japan to the coasts of Canada, the United States, and Mexico. It lives in the cold waters of the Pacific Ocean at temperatures of 60 degrees Fahrenheit or colder, in both shallow waters and at depths of up to 1500 meters or more. It is a solitary animal that spends most of its life alone.

Giant Pacific octopus diet
The adult Giant Pacific Octopus is a carnivorous and stealthy hunter that eats a wide range of seafood and crustaceans, most commonly crabs, clams, and other mollusks. It ambushes its prey using camouflage, propulsion, and the strong grip of its eight arms. The octopus then returns to its rocky den to settle down and enjoy a satisfying meal.
Reproduction
Giant Pacific Octopuses live for only four to five years in the wild, but they are still considered one of the longest-living octopi’s species. Octopuses usually die shortly after breeding. After mating, the female lays up to 74,000 eggs or more in a deep den or cave and stays there for seven months to watch over them. During this time, the devoted mothers will not venture out for food, and shortly after the young hatch, the mother dies. This behavior makes it difficult to determine the population numbers of the Giant Pacific Octopus.
Self-Defense
To protect themselves from predators, Giant Pacific Octopuses use camouflage and color change, as well as their strong arms for defense.

Giant Pacific Octopuses can grow to a span of 9 meters from arm tip to arm tip and weigh 20 kilograms.
