If you think that 9 months is a long time to wait for a baby, be glad that you are not an octopus. Since these particular baby octopuses had such a long time to develop, they could swim and hunt soon after their hatching. Ultimately, this level of dedication is extreme even for octopuses. It can be found in both the Pacific and Atlantic Oceans. There, the team encountered a single female octopus of the species Graneledone boreopacifica. A deep-sea octo-mom, Graneledone boreopacifica, was recorded by the Monterey Bay Aquarium Research Institute (MBARI) to brood her eggs for 53 months, or almost four and a half years. Near the octopus are two Lithodid crabs and a non-brooding Graneledone can be seen above and to the right of the brooder. Researchers believe that the octopus was able to survive the lack of food because of her inactivity, which kept her metabolic demands low.

For instance, emperor penguins, which have the longest egg incubation for a penguin , spend 64 days on average tending their single egg (though unusually, this duty is performed by the dads rather than the mums). Blake (Eds.). For most shallow-water species, the brooding time lasts some three months. They are also thought to be the longest living. This obviously had an impact on the octopus, and researchers watched as she grew paler, lost weight, her skin sagged, she her eyes grew cloudy. Over the course of the next four and a half years, the team made a total of 18 visits to see this octopus. The title goes to the deep-sea Graneledone boreopacifica, an octopus that guards its eggs for an astounding 4.5 years. The work was published in PLoS One this week. Likewise, laboratory studies have linked lower temperatures to longer brooding periods in cephalopods, but direct evidence has not been available. The researchers from MBARI, led by Bruce Robison, initially encountered the octopus (pictured above) in April 2007. This clutch size was between 155 to 165 eggs. Most octopuses live only 1 to 2 years, so this octopus brooded her eggs for the … FULL-TIME JOB: A deep-sea octopus (Graneledone boreopacifica) is shown on a ledge near the bottom of Monterey Canyon, California, about 1400 metres (4600 feet) below the ocean surface.

As mentioned, we still don’t know the full lifespan of the newly discovered species that broods for 4.5 years. The Deep Sea Octopus, Graneledone boreopacifica. Moreover, most octopus species don’t live very long. This record was recently broken by another species known as Graneledone boreopacifica, another deep sea resident which was observed brooding her eggs for 53 months! It lives in both the Atlantic and Pacific in the deep ocean. This is the longest incubation period of any animal, both in absolute terms and in proportion to the lifespan of the animal. Female octopuses generally brood over eggs for 1 to 3 months. Class Cephalopoda. Megaleledonidae is a family of octopuses in the superfamily Octopodoidea.It was formerly placed in the family Octopodidae sensu lato as the subfamily Megaleledoninae but more recent studies have raised this taxon as a valid family.. Reproduction. Molluscs exhibit fascinating biological and evolutionary innovations, including a diversity of body plans and highly specialized structures (e.g. Most species stay in the 12–18 month range, but as I said, now we’re picking up all the deep sea varieties and things are changing. Obviously, the 53 month vigil of the Graneledone boreopacifica blows the shallow-water species out of the water. The deep-sea octopus mum (Graneledone boreopacifica) was first spotted by a team of divers from the Monterey Bay Aquarium Research Institute (MBARI) in May 2007, just a … 9 (7): e103437. 2014; 9: e103437. At 53 months, it is by far the longest egg-brooding period ever reported for any animal species. Led by Bruce Robison, a team of MBARI researchers has spent 25 years diving into the depths of Monterey Canyon to survey deep-sea life.In May 2007, a female Graneledone boreopacifica … [1], The type specimen was collected in the Pacific Ocean (50°N, 151°E) and is deposited at the Zoological Institute in Saint Petersburg, Russia. In fact, these are the most highly developed octopus hatchlings known to date. Previously, the longest brooding octopus was the deep-sea Bathypolypus arcticus, which had a brooding time of some 14 months in the lab. "Deep-Sea Octopus (Graneledone boreopacifica) Conducts the Longest-Known Egg-Brooding Period of Any Animal".

PLOS ONE , 30 Jul 2014 … Octopuses come in all shapes and sizes and inhabit diverse regions of the ocean. Megaleledonidae are known to produce both fewer and larger offspring that octopods that live in more tropical climates. Gestation periods can last for months, depending on species and conditions: one deep-sea octopus, Graneledone boreopacifica, has a … Regardless of how their nutritional needs are met, female G. boreopacifica spend a long time brooding. Scientists associated with the study also note that it is possible that the octopus nibbled on some passing crabs or consumed some of the damages eggs; however, no such feedings were actually witnessed and the octopus did not eat a crab that the team offered her. This is the longest known brooding period of any animal on the planet. The eggs of Graneledone boreopacifica are tear-drop-shaped capsules the size of small olives. deep-sea octopus (Graneledone boreopacifica). '” Ultimately, the eggs hatched in between the team’s September and October 2011 trips. This also makes it the longest living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone. [5] [6] Inga underarter finns listade i Catalogue of Life. However, as previously mentioned, the toll on the mother is rather steep. They typical lifespan is just one to two years. These reactions enable organisms to grow, reproduce, move and otherwise respond to their environments. [5], Hochberg, F.G. 1998. Indeed, nearly all cephalopods (a grouping that includes squid, nautilus, octopus, and cuttlefish) are only known to live one or two years, which this octopus beats during its brooding time alone. Once this period is over, the octopus usually dies. Most cephalopod’s (i.e. G. boreopacifica octopuses are the longest brooding animals on the planet. And despite the fact that little is known about the deep-sea dwellers, scientists speculate that the baby octopuses’ long development period is due to the slow metabolism that is brought on by colder temperatures (which means that the cold waters are likely a contributing factor to the mother’s sparse eating habits). The giant Pacific octopus is also relatively long-lived, with a lifespan of up to 5 years. That is actually a record brooding period in the entire animal kingdom! Amazingly, over the course of the octopus’ 53-month brooding period, the researchers never witnessed her feeding. Generally, a female octopus will have one reproductive period in its life, and brooding will last about a quarter of its life.
