The animals are members of the genus Grimpoteuthis, which in turn is a subset of the family Opisthoteuthidae, the umbrella octopuses.There are distinctions between the dumbo octopus species, but all are bathypelagic animals found on or near the deep ocean floor. Worldwide having been found in New Zealand and Australia, Monterey Bay, California; Oregon, Philippines and in Papua, New Guinea
The dumbo octopus (Grimpoteuthis) is a deep sea animal that lives on the ocean floor at extreme depths of 9,800 to 13,000 feet.They are small animals, around 8 inches tall, and have a pair of fins located on their mantle—their namesake—and webbing between their arms.
There are 13 species of dumbo octopuses. From studying dead octopuses, scientists know females contain eggs at different maturation stages. Deep on the ocean floor, there lives an octopus with a name straight out of a Disney movie. 5.
The name "dumbo" originates from their resemblance to the title character of Disney's 1941 film Dumbo, having a prominent ear-like fin which extends from the mantle a… It is hypothesized that the female can then distribute this sperm to the eggs at any given time based on environmental conditions.
Dumbo Octopus The dozen or so species that make up Grimpoteuthis are called Dumbo octopuses because of the two large fins—one on either side of the mantle—that protrude like ears. The genus has a distinct habit of swimming.
The animals are members of the genus The average size of a dumbo octopus is 20 to 30 centimeters (7.9 to 12 inches) in length, but one specimen was 1.8 meters (5.9 feet) in length and weighed 5.9 kilograms (13 pounds). The octopus behavior conserves energy, which is at a premium in a habitat where both food and predators are relatively scarce.NOAA Okeanos Explorer/Wikimedia Commons/Public DomainThe dumbo octopus' unusual reproductive strategy is a consequence of its environment. Grimpoteuthis Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Order: Octopoda Family: Opisthoteuthidae Genus: Grimpoteuthis Robson, 1932 Type species Cirroteuthis umbellata Fischer, 1884 Species 14, see text Grimpoteuthis is a genus of pelagic umbrella octopuses known as the dumbo octopuses. Females carry multiple eggs in various stages of maturation, suggesting that they have no optimal breeding period. The fins are in fact primarily used for stabilization and steering.Females have no distinct period for breeding. The female stores the sperm to use when conditions are favorable for laying eggs. Females lay eggs on shells or beneath small rocks on the seafloor.
There is no special octopus breeding season.
This rare animal displays other unusual traits that are adaptations to life in the cold, pressurized depths of the ocean.NOAA OKEANOS EXPLORER Program, Oceano Profundo 2015; Exploring Puerto Rico's Seamounts, Trenches, and Troughs/Flickr/CC BY 2.0There are 13 species of dumbo octopuses. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. The young octopuses are large when they are born and must survive on their own. The Dumbo octopus is the deepest-living genus of all known octopuses. (2003).
It lives at least 13,100 feet (4,000 m) below the surface. Male octopuses have a separate protuberance on one of their arms that carries an encapsulated sperm packet to the female.
The last entry on the list, Grimpoteuthis wuelker, is as of yet unconfirmed by the marine biology community to be a Dumbo Octopus. It has been found that there are seventeen different species of Umbrella Dumbo octopi, referred to as "umbrella octopuses" because once they … 71, no.
A dumbo octopus lives around 3 to 5 years.Some interesting, yet lesser-known facts about the dumbo octopus include:NOAA OKEANOS EXPLORER Program, Oceano Profundo 2015; Exploring Puerto Rico's Seamounts, Trenches, and Troughs/Flickr/CC BY 2.0 South African Journal of Marine Science Suid-Afrikaanse Tydskrif Vir Seewetenskap.
"Collins, Martin; Vecchione, Michael; Young, Richard E. (2003). The average weight of the creatures is unknown.The dumbo octopus comes in various shapes, sizes, and colors (red, white, brown, pink), plus it has the ability to "flush" or change color to camouflage itself against the ocean floor. Collins, Martin; Vecchione, Michael; Young, Richard E. (2003). "Vecchione, M., U. Piatkowski. A Dumbo octopus is a marine animal of the genus Grimpoteuthis, which is a genus of Umbrella octopus.
Some believe that it may be a sub-species of the grimpoteuthis plena or grimpoteuthis umbellata species as opposed to being its own stand-alone species.
Deep beneath the sea surface, seasons have no significance, yet food is often scarce. NOAA Okeanos Explorer/Wikimedia Commons/Public DomainThe dumbo octopus is neutrally buoyant, so it may be seen hanging suspended in the water.
One arm of a male octopus has a special protuberance used to deliver a sperm packet into the mantle of a female octopus. 20:421-428.
