Animal Planet - The giant octopus of the ocean (Enteroctopus dofleini)
- 6 years ago
The giant Pacific octopus is considered the largest octopus species in the world and inhabits the northern Pacific Ocean off the United States up to Alaska and around Japan. The largest individual on record weighed an impressive 600 pounds and measured 30 feet across in length. On average, though, these octopuses weigh closer to 110 pounds and measure 16 feet across once fully grown. Like other octopuses, the giant Pacific octopus is extremely intelligent and has been observed opening jars and mimicking other species.
Octopuses are sea animals famous for their rounded bodies, bulging eyes, and eight long arms. They live in all the world’s oceans but are especially abundant in warm, tropical waters. Octopuses, like their cousin, the squid, are often considered “monsters of the deep,” though some species, or types, occupy relatively shallow waters.
Most octopuses stay along the ocean’s floor, although some species are pelagic, which means they live near the water’s surface. Other octopus species live in deep, dark waters, rising from below at dawn and dusk to search for food. Crabs, shrimps, and lobsters rank among their favorite foods, though some can attack larger prey, like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth. The octopus performs its famous backward swim by blasting water through a muscular tube on the body called a siphon. Octopuses also crawl along the ocean’s floor, tucking their arms into small openings to search for food. Seals, whales, and large fish prey on octopuses.
If threatened, octopuses shoot an inky fluid that darkens the water, confusing the aggressor. The octopus can also change to gray, brown, pink, blue, or green to blend in with its surroundings. Octopuses may also change color as a way to communicate with other octopuses. Octopuses are solitary creatures that live alone in dens built from rocks, which the octopus moves into place using its powerful arms. Octopuses sometimes even fashion a rock “door” for their den that pulls closed when the octopus is safely inside.
Giant Pacific octopuses only live an average four to five years in the wild, yet they are still considered one of the longest-living octopus species. Octopuses typically die shortly following breeding. After mating, a female will lay up to 74,000 eggs or more in a deep den or cave and live there for seven months watching over them. During this time, dedicated mothers won’t venture out for food, and shortly after the young hatch, the mother will die. Because of this behavior, it is difficult to know population numbers of the giant Pacific octopus. Even though these octopuses are still commercially fished in both North America and Japan for food and bait, populations have been naturally resilient so far.
