Giant pacific octopus has fat and round-shaped head. Fish and Wildlife Service, which regulates the nation’s wildlife trade, requires that import declarations be filed for all species coming in, as well as a more detailed invoice for each wildlife shipment. The Seattle Aquarium holds an annual Valentine’s Day party to mark the would-be mating of its giant Pacific octopuses (the world's largest species, sometimes weighing more than 100 pounds, with an arm span of up to 20 feet). Slemp isn't opposed on principle to keeping these big-brained, unusually smart mollusks as pets, but he won’t sell octopuses to just anyone. Some would eat their own arms,” he says. Aquarium hobbyists can be allies in this cause, she argues, contributing to public and scientific understanding of these previously overlooked animals: "When people keep octopuses at home, they really get an attachment to them, and share that appreciation.". “If there is one thing that we know about mimics,” Shaw writes, “it is that they are rare.” He notes that their Indonesian coastal habitat is being wiped out by runoff and mining and that they do poorly in captivity, which means many mimics likely die so one can survive a few months in a tank. "I assumed it was a small sea cucumber and dismissed the comment," he writes on the Cephalopod Page. They have relatively short lifespans with some only living for 6 months the giant Pacific octopus can live for approximately 5 years. Most species live only one to two years, and a newly imported octopus may have just weeks left. Populations of giant Pacific octopus are thought to be stable in the north Pacific and increased popularity in the human food market has increased their value as by … All rights reserved. Giant pacific octopus (Enteroctopus Dofleini) is a long-lived and large cephalopod. Before a courtship can begin between two octopuses, they first need to find each other. Lifespan The giant Pacific octopus has a long lifespan for an octopus — about three to five years. Octopuses typically die shortly following breeding. On the Cephalopod Page website, which Wood edits, aquarist Christopher Shaw and University of California, Berkeley, biologist Roy Caldwell posted a package of articles under the headline, “Mimic Octopuses: Will We Love Them to Death?”. The giant Pacific octopus is the biggest octopus species. One, Pete’s Aquariums in Fishkill, New York, lists blue rings at $199.99 but notes that they’re sold out. During their life span, many octopus … But it doesn’t compile import counts for octopuses and other unlisted species or readily release information from the invoices. They’re big. "If anything,” says the sales manager at one aquarium-animal import company who requested anonymity because he was speaking without authorization, “I’ve seen a downturn over the years.". The gestation period of the female is one month. Blue rings’ lethality, coupled with their dazzling eponymous markings, exert a powerful allure on some aquarium aficionados—“daredevils,” Slemp calls them. And they worry about the danger posed to naïve hobbyists by the alluring, but lethally venomous, blue-ringed octopus. One of the most persistent myths regarding octopus and squids is that of the giant squid -- a massive creature who sinks ships and feasts on humans. Internal Morphology: Like other octopuses, these are cool-blooded creatures, with three hearts that control their intricate circulatory and nervous systems, and nine brains to control different movements; the color of the blood is blue. The giant Pacific octopus, is one of two largest species of octopus, may live for as much as five years however all animals live longer in their own environments. Rather than crawling for cover like most octopuses, [the octopus] reared up while pulling back her first two pair of arms [and] exposing her mouth. An adult of these cephalopods has enough strength to move more than 700 pounds. Custom ordering also enables responsible vendors to evaluate purchasers and advise them about best practices. 2020 National Geographic Partners, LLC. Even if that demand continued exponentially, it would be legal: None of the 300-plus known species of octopus is listed under the Convention on International Trade in Endangered Species of Fauna and Flora (CITES), which regulates cross-border trade in wildlife, or the U.S. She felt "something soft and squishy" inside one rock oyster shell. Rhyne's team found many discrepancies between the import declarations and the more detailed invoices. You guessed it: it’s the octopus! Which creature has three hearts, eight arms and a doughnut shaped brain? But much remains unknown about them, especially about mimics, including how many inhabit the shallow seabeds off Sulawesi, Indonesia, and other Indo-Pacific islands where they’re found. If it releases the ink in a confined space and then fails to move away in time, it will possibly fall sick or even die by ingesting its own venom. U.S. imports of the highly venomous greater blue-ringed octopus have outpaced those of all other species, according to the sparse available records. More blue-ring fatalities may go unidentified, however, because the bites are painless and the mode of death—respiratory paralysis—can be caused by other toxins and nerve, muscle, and lung conditions. “This is not an animal to be taken on lightly.” The fact that octopuses seem very intelligent deters some people, who have qualms about treating them badly, from buying them. 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. After hatching, the baby octopus(or larvae) take on the role of plankton, drifting around the ocean feeding on neuston (dead food) as opposed to hunting live prey. The store’s receptionist hung up abruptly when I identified myself and asked about their blue rings. By and by, the juveniles get drifted by the ocean current for about three months, feeding only on planktons. He urges even public aquariums to resist the lure of this trophy: “I honestly fear that if we cannot stem their collection, there will be no mimics to wonder at in a very few years.”. Reproduction. Giant Pacific Octopus Facts for Kids. The organization cheers the celebrated flight of an octopus called Inky from New Zealand's National Aquarium in 2016: "His bold escape should send a message to aquariums to keep their tentacles off octopuses for good. The purchase is also a short-term investment. “It’s cool now to be a nerd, and they’re the ultimate nerd animals.” So it’s only natural that ardent aquarium hobbyists and newly sea-struck fans alike may get the urge to have their own eight-legged marvels. “Some would crawl up the containers, out of the water, and just dry out. Once found, they would use their arms (not to be confused with tentacles) to hold the prey tightly, and then use their sharp parrot-beaklike mouth to puncture the flesh and tear through. This may reflect a lack of information—for example, in the case of the mimic octopus. Adults usually weigh around 15 kg (33 lb), with an arm span of up to 4.3 m (14 ft). Because they’re solitary, they can fare better in captivity than animals whose rich familial and social lives can’t be reproduced there—as long as they're provided a suitably rich environment. Most common octopus species don’t live longer than two years. The striped, or wunderpus, octopus was discovered in the 1980s. This stage on an average lasts for 30-90 days. However, to attain sexual maturity, they need to wait for a whole year during which time they are approximately 20 pounds. The Giant Pacific Octopus (or, the North Pacific Giant Octopus) is the world’s largest and longest-living octopus species that are known for their high intelligence. That’s partly because records of imports of cephalopods to the United States are spotty and out of date.

The service uses the volume of shipments received to determine staff needs and resources at the nation’s ports of entry. Wood and other experts fear that too much enthusiasm may endanger two of the most dazzling and mediagenic, but little studied and potentially rare, species: the striped or wunderpus octopus (discovered in the 1980s) and its cousin, the mimic octopus (identified only in 1998). Larvae hatch from a cluster of eggs and are on average 9.5 to 10.1 mm in length. Your email address will not be published. The female Giant Pacific Octopus is an example of genuine parental care, guarding the eggs for almost seven months until they hatch. Giant Pacific Octopus at SEA LIFE. James Wood also hails the idea. Their saliva contains the potent nerve toxin tetrodotoxin, the same compound that makes California newts, harlequin frogs, and fugu pufferfish liver so deadly. Little is known about the behavior of these enigmatic creatures. Reproduction in whole or in part without permission is prohibited. During this time, life is too hectic, and thousands of them fall prey to different creatures of the sea. Some robust common species, such as the California two-spot octopus, get along relatively well in captivity. Conclusive research is going on about an entirely new species of giant octopus, closely related to the Giant Pacific, which was discovered by marine scientists in Alaska in December 2017. The Giant Octopuses dwell in the cold temperate coastal waters up to a depth of 330 feet or more in the kelp forests, rocky areas, and caves. As with most creatures, the octopus's main purpose in life is to reproduce. However, if it knew just what was waiting for it soon after, it might think twice.

The largest Giant Pacific Octopus ever caught measured about 30 feet across and weighed over 600 pounds. They’re master escape artists, able to slop through thin cracks and out of all but the most securely sealed tanks—one of many traits that make them uniquely challenging and costly animals to keep. © 2020 (Animal Spot). A DNA analysis has suggested that this octopus might have three subspecies, with one being in Alaska, one in Japan, and the third one in Puget Sound, though nothing has been officially confirmed as yet. One import of a mimic was recorded in 2008, two in 2009, and 30 in 2011, the last year available. The result was a suggestive snapshot of the marine wildlife trade into the U.S., but even this small trove of data—all that we have on octopus imports—is outdated and imperfect. The vision is exceptionally sharp. "Ripley’s Aquarium of Canada is home to a giant Pacific octopus (Enteroctopus dofleini). These animals are not at all aggressive (but somewhat shy and timid), and would rarely attack or bite humans unless threatened. But trade volumes and trends are largely matters of anecdote and speculation. The Giant Pacific Octopus: Enteroctopus dofleini. The giant Pacific octopus is a very intelligent animal that can learn to open jars, play with toys and interact with — and even recognize — its handlers. The reclusive, delicate mimic octopus doesn’t do well. The octopus lifespan is relatively short, with some living lives that last only six months, but it varies depending on species. Caldwell recounts a close escape. The Giant Pacific octopus hunts for food at night and has a lifespan of four years. Instead, they’re adopting custom ordering, which reduces excess shipments of animals and therefore mortality. We'd like to introduce you to Hank, he's a Giant Pacific Octopus and the star of our brand new attraction, Octopus Hideout.

Their arms span up to 4.3 m or 14 ft. Endangered Species Act (ESA). The giant Pacific octopus grows bigger and lives longer than any other octopus species. Wunderpus and mimic octopuses are the ultimate quick-change artists, hiding in plain sight by impersonating everything from rocks and seaweed to sea snakes and lionfish. Many other octopuses go through a lifespan in one year, from egg to end of life. "It's completely possible we will see an influx," he says. The short life span and reclusive tendencies of this species have proved a challenge for researchers. Your email address will not be published. “We have to make sure they have the background, make sure they have the knowledge to treat the things that pop up.". Scientists have … Description. Octopuses are well-known masters of camouflage and skillful escape artists, but they aren't exactly famous for their social skills. Individuals reach sexual maturity at around two to three years of age, though they only live to be about four to five years old. Such traits make octopuses stars of the page and screen.

The primary diet of the Giant Octopus includes various fishes, crabs, clams, cockles, fish eggs, abalone, scallops, other octopuses, marine birds like seagulls, and even small sharks. Any downturn also reflects the efforts of Wood and other experts to educate hobbyists and vendors about the costs and hazards of keeping these demanding super-mollusks. The adult or relatively larger octopuses practically do not have predators. All octopuses probably carry some venom, but only the various golf ball-size blue-ringed species, which range from southern Japan to Australia, are known to pack a lethal dose. One of those pop-ups is the octopuses themselves. The ink of this animal is poisonous. Incredible Adaptations. NOAA funded Roger Williams University's Marine Aquarium and Biodiversity Trade Flow project to digitize and analyze the information in them. Both the male and female octopuses die soon after mating. Giant Pacific Octopus Habitat “All the reasons you would use enrichment for vertebrates apply to octopuses,” Wood says. (Ross is now with the Albright Laboratory, a coral-reef research and restoration facility affiliated with the aquarium.) “Sometimes they hitchhike along on [chunks of coral reef], and you don’t even know you have one,” Wood says. "The U.S. and other countries do not have any system in place to monitor the trade and provide data" for wildlife, such as octopuses, not listed under CITES. Blue-ring bites occur each year in Australia, but timely, vigorous artificial respiration usually prevents fatalities; only three have been confirmed during the past century, none involving aquariums. Although there is no directed fishery for octopus in Alaska, octopus, in particular, the giant Pacific octopus, are caught incidentally in Alaskan commercial trawl, longline and pot fisheries. 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. Lifespan The average longevity of the Giant Pacific Octopus is 4.5 to 5 years in both captivity and the wild. To determine whether and how imports of octopuses and other aquarium species are affecting wild populations, it would help greatly to know just how many are being imported. In addition to their high prices and expensive diets—heavy on live crabs and shrimp— octopuses need large, escape-proof tanks with ample hiding places, unassailable fixtures to withstand their powerful arms and inquisitive tampering, and no fish or other companions (they'll eat them). Biologist Rich Ross, who once worked in the commercial aquarium trade, proposes a private-sector solution to the information drought: “a cooperative of responsible saltwater aquarium dealers” that could both track the trade and promote sustainable practices. “Reading all the articles out there, people see themselves in these animals,” says a salesman at one leading marine-animal importer, who asked not to be named because he spoke without authorization.

But when he cracked the shell open, "a tangle of arms covered with small iridescent blue spots spewed from the fissure,” he wrote on the Cephalopod Page. To make up for its relatively short lifespan, the octopus is extremely prolific. During this period, the female octopus would live inside her cave without taking any food, using its arms to fan the eggs, and gushing streams of water rich in nutrients and oxygen. The giant Pacific octopus starts life as tiny as a grain of rice, living in the surface water of the oceans for the first three months of their life. “Octopuses are very charismatic,” says James Wood, a marine biologist turned aquarium operator based near Palm Beach, Florida. Average Length: 3.3 ft – 6 ft 7 in. The average longevity of the Giant Pacific Octopus is 4.5 to 5 years in both captivity and the wild. Those that manage to survive and attain about 5 grams of body weight begin to settle at the bottom of the ocean. "Life in a tank is no life at all for sensitive, intelligent octopuses," declares People for the Ethical Treatment of Animals. Others, such as the fabled but delicate mimic, do much worse. Find out about these and other octopus facts. But, Ross adds, some conspicuous aquarium keepers accept the high costs and turnover as the price of displaying such charismatic creatures: “They think of these animals as cut flowers.". Giant Pacific Octopus are semelparous, meaning they reproduce once then die. Lab tests have shown that they can be ‘friendly’ and learn to use tools, open jars, mimic other octopuses, and even solve mazes, or recognize human faces. In Seattle, the artists, writers, musicians, and scientists of the Cephalopod Appreciation Society gather each summer to celebrate octopuses and their squid and cuttlefish cousins in image, word, and song. Found in a small region of the Pacific Ocean, these creatures produce thousands of eggs, making their populations naturally resilient, though their exact numbers are not known. However, they are also caught for public aquariums and as bait in other fisheries. It may come as a surprise for many, but the death of these creatures is related to their reproduction process. The female would hang the eggs in many strands from the roof of a cave deep down in the ocean.

Some, such as the California two-spot octopus, appear to fare relatively well in captivity. Even so, it’s unclear whether all the fascination is hurting octopuses. Every year, up to 3,500 tons of these octopuses are caught in North America, where fishing and consuming octopus is not a taboo. Males possess a modified sex arm called a hectocotylus that stores long ropes of sperm. “I get asked all the time, ‘Can you get octopuses?’” says Jeff Slemp, proprietor of a store called Cuttlefish and Corals Sustainable Saltwater Aquariums, in Portland, Oregon. [ Average Weight: 22 – 26.5 lbs. Vendors and importers sometimes conflate the two species, but that doesn’t stop them from offering both to collectors willing to pay $200 or more for one.

Blue rings carry enough nerve toxin to kill 10 or more humans. A male can mate with several females, but the female can reproduce only once in their lifetime. The largest specimen of this species to be scientifically documented was an animal with a live mass of 71 kg (156.5 lb). Each captive or aquarium pet is known to have a unique temperament and personality and can be both playful and destructive.

Those almost certainly weren’t the only blue rings that came in. These cephalopods are polygamous. Demand in the U.S. seems to have begun growing in the few years for which official import data have been released, although the numbers were small. Octopuses in general usually live no more than a year! The male dies a few months afterwards, while female dies shortly after the eggs hatch.

The IUCN Red List has not enlisted/categorized this octopus species. When it comes to mating, a single female will move out in search of a male that should be typically larger than it. By the time the young ones are a year old, they grow to around 2 pounds. A slew of research papers, popular books, magazine articles, and nature documentaries celebrates their improbable intelligence (a mollusk with a vertebrate-size brain and problem-solving ability! For octopuses, mating is a pretty subdued affair. (See what happened at the most recent CITES conference.). Octopus are mollusks, which means they are from the same phylum (or family) as slugs, snails, cuttlefish and … ", University of Lethbridge animal psychologist Jennifer Mather, a pioneering researcher into octopus cognition and personality, sees octopuses as "the poster child for invertebrate animal welfare"—worthy of the same rights as animals that look more like us.

Once this task is completed, it will die. The giant Pacific octopus is a cephalopod species native to the northern Pacific Ocean. The National Oceanic and Atmospheric Administration (NOAA), by agreement with the Fish and Wildlife Service, obtained the invoices for imports of aquarium species during three complete years (2008, 2009, and 2011) and parts of 2004 and 2005. The length of time that passes between hatching, reproduction and death varies among octopus species. A giant Pacific octopus will live a solitary life until the very end, at which point it will seek out a mate, reproduce and die shortly thereafter. The lifespan of giant Pacific octopuses is characterized by a fast growth period that continues throughout its entire life of 4 to 5 years. Arms: Four pairs of arms extend from its mantle, with each pair having about 280 suckers or suction cups, which in turn are further made of many thousand chemical receptors that give them the power of sharp smell and taste. Body/Appearance: The skin is reddish pink, having faint venation patterns all over. ), “Word got out,” Ross says. When he began his research, he kept his octopuses in bare containers. An octopus's garden The adult giant Pacific octopus eats a wide assortment of seafood including crabs, clams and other mussels. Such cavalier attitudes trouble Wood, who studied octopuses as a faculty member at the Bermuda Institute of Ocean Sciences. The range of this species range extends throughout the Pacific Ocean, starting from the south of California to Alaska, stretching to the west up to the Aleutian Islands and Japan. It can lay between 120,000 and 400,000 eggs which are intensively cared for by the females. Its aggressiveness and predatory behavior as envisioned by authors like Jules Verne is the stuff of legend, but the giant squid does exist. During mating, he inserts the rope of sperm, called a spermatophore, into the female’s oviduct. Other vendors still offer them, even online.
