For an adult-age giant Pacific octopus, the average weight is 15 kg (33 lb) and the average arm span is 4.3 m (14 ft). Some octopuses exhibit the ability to alter speeds of sodium and potassium ion movement across cell membranes, allowing them to live in very cold water. It was recorded in Alaskan Aleutian Islands and Baja California. Large and in Charge – These creatures can really live up to the name “giant” Pacific octopus. [30] One study found that higher water temperatures accelerated all aspects of reproduction and even shortened lifespan by up to 20%. Their arms span up to 4.3 m or 14 ft. The giant Pacific octopus is the biggest octopus species. [1] To make up for its relatively short lifespan, the octopus is extremely prolific. It can be found from the intertidal zone down to 2,000 m (6,600 ft), and is best adapted to cold, oxygen-rich water. Like other species of octopus, they can change colour and have excellent eyesight. Octopuses have been found to migrate for a variety of reasons. During this time, it leads a solitary existence, breeding only one time. After mating, the female stops hunting. The Tomamae Giant Pacific Octopus FIP aims to revitalize the region’s fisheries by improving the sustainability of fishing practices through the establishment of a science-based management plan for the octopus fishery, which is managed by the Kita-Rumoi Fisheries Cooperative. The giant Pacific octopus or ‘Enteroctopus Dofleini’ is the biggest known octopus species. After mating, the male's physical condition deteriorates. Eggs hatch in about 6 months. [16] The octopus brain has folded lobes (a distinct characteristic of complexity), visual and tactile memory centers. The female stops eating during this care and her life ends soon after the eggs hatch. This is a state of hypoxia. The Giant Pacific octopus, Enteroctopus dofleini, is a contender for being the largest of all octopus species, but it turns out it is actually at least two distinct species. Increased seawater temperatures also increase metabolic processes.

The eggs and paralarvae support zooplankton filter feeders, such as baleen whales, some species of sharks, and many species of fish. Ocean acidification lowers available carbonate ions, which is a building block for calcium carbonate (CaCO3). [29] Fish and octopuses move from the deep towards the shallow water for more oxygen. The only member of this genus that deserves the common name "Giant octopus" is Enteroctopus dofleini. Size Range: 3-5 meters and averaging 50kg (110lbs) Identifying Features: Giant Pacific Octopuses as their name implies are found in the northern part of the Pacific Ocean. Location: Japan, Siberia, Alaska to Mexico. [16] To avoid these dead zones, octopuses must move to shallower waters which may be warmer in temperature and less oxygen-rich, trapping the organism between two low-oxygen zones. [1] What effects these toxins have on octopuses are unknown, but other exposed animals have been known to show liver damage, changes in immune systems, and death. This is the world’s largest species of octopus. For example, a stone carving found in the archaeological recovery from Bronze Age Minoan Crete at Knossos (1900–1100 BC) has a depiction of a fisherman carrying an octopus.

Scientific name: Enteroctopus dofleni. Although many eggs are laid and hatch, most hatchlings are eaten before they reach adulthood. History. Joshua Rosenthal, at the University of Puerto Rico's Institute of Neurobiology has found that they have altered protein synthesis, and can speed up potassium channels in cold water, to keep up with sodium ion exchange. [17], The giant Pacific octopus is considered to be long-lived compared to other species, with lifespans typically 3–5 years in the wild. The giant Pacific octopus lives in the Pacific Ocean off the coasts of Russia, Japan, Korea, British Columbia, Alaska, Washington, Oregon, and California.

Adults usually weigh around 15 kg (33 lb), with an arm span up to 4.3 m (14 ft). [18] Eggs are coated in chorion, and the female attaches the eggs to a hard surface. Death is typically attributed to starvation, as the females stop hunting and instead protect their eggs; males often spend more time in the open, making them more likely to be preyed upon. [16] DNA techniques have assisted in genetic and phylogenetic analysis of the species' evolutionary past. Interesting Facts About the Pacific Octopus.

As these micro-organisms decompose, oxygen is used up in the process and has been measured to be as low as 2 parts per million (ppm). He stops eating and spends more time in open water. After reproduction, they enter a stage called senescence, which involves obvious changes in behavior and appearance, including a reduced appetite, retraction of skin around the eyes giving them a more pronounced appearance, increased activity in uncoordinated patterns, and white lesions all over the body. The giant Pacific octopus is one of the largest kinds of octopus in the world. He is now looking into whether individuals can alter their protein synthesis in response to changing temperatures, or if it is done over long-term adaptations. Some research suggests that fishing other species have aided octopus populations, by taking out predators and competitors. [31] Other studies concur that warming climate scenarios result in higher embryo and paralarvae mortalites.[32]. [1][8] A UN catalog of octopuses sizes E. dofleini at 180 kg (396 lb) with an arm length of 3 m (9.8 ft). However, the Southern Red Octopus is very small compared to the other members of Enteroctopus and only grows up to about 8.81 pounds (4 kilograms) – this is still “big” compared to many other octopus species.
