Grimpoteuthis[1] is a genus of pelagic umbrella octopuses known as the dumbo octopuses. Octopuses (or octopi, if you prefer) are cephalopods, invertebrates that also include squid and cuttlefish. Females have a much more prevalent gelatinous body type with size being more width than length, having 1.5 to 2 time more short arms.
In previous studies, it has been demonstrated that blind octopuses are able to detect sounds inside water, be they from an incoming boat, or from taps drummed on the walls of the tanks they were in.
These patches function to detect (unfocused) light.
Octopuses can open clamshells, maneuver rocksâeven dismantle the filtration systems of an aquarium tank.
Earwigs lay eggs in your ears; Answers 1. Interestingly though, both species hear best at a frequency of 600Hz,” Yan said, quoted by the BBC News.
Solitary animals, they typically live alone, sometimes in dens they build from rocks, sometimes in shells they pull over on top of themselves.
[31] Dumbos hover above the sea floor, searching for polychaete worms, pelagic copepods, isopods, amphipods, and other crustaceans for food. Moving these hairs in humans causes a difference of electrical potential in auditory nerves, which is transmitted to the brain and processed into the auditory sensation.
Or, perhaps they even could make sounds to communicate among themselves.”. Little wonder, considering they are a bit unusual.
", Vecchione, Michael; Young, Richard E. (2003). [29] Movement of the arms can be used to help the animal move in any direction. Other differences include females having broadly U-shaped shells, larger eyes, and gills with six lamellae. “That indicates that squid have a better hearing capability than the octopus. [33] [3] Prey include crustaceans, bivalves, worms and copepods. “The key question which I would like to investigate is what kind of sounds are they listening to? Some even make a door for themselvesâa rock pulled into place once theyâre safely tucked into their homes. Octopuses mostly feed on crabs, shrimp, and mollusks. [2] The average life span of various Grimpoteuthis species is 3 to 5 years. To most people, these might appear like ears, but they are actually fins. Grimpoteuthis is a genus of pelagic umbrella octopuses known as the dumbo octopuses.

Specimens have been found off the coast of Oregon, the Philippines, Martha's Vineyard, the Azores, New Zealand, Australia, California, Gulf of Mexico, Papua, and New Guinea. Find out about these and other octopus facts. Not all the octopus species have fins. The holes on either side of an octopus's main body ("head") are funnels or siphons for water flow, but not an auditory organ of any kind.
Therefore, the fins of the Flapjack Octopus distinguish it from the other octopus species. Octopuses are highly intelligent animals, masters of camouflage that have evolved an array of tricks over tens of millions of years to avoid or thwart would-be attackers.
