For the octopus, almost any hand will do so.
New studies have been published on Thursday show that octopus has the ability to use any of the eight limbs to perform tasks such as achievement, tip or grab.
“These animals are incredible multifunctionists, so they can take several steps on one hand and on their knees at the same time,” said Kendra Burresch, a research biologist located in the Marine Biological Laboratory Woods Hole, Massachusetts, and the author of the study. “Some other animals have different specializations for different parts of the body, while the octopus is certainly adapted to use any hand in any situation in any situation.”
Conclusions, published on Thursday, reveal new information on how loudly flexible creatures coordinate in the animal kingdom. Further research could help researchers understand how animals have developed such neurologically complex motor skills.
This work could also help create robots for medical purposes or to investigate hard -to -reach areas. The octopus is increasingly used as the inhalation of soft robots, and this new hand movement inventory could give engineers new insights, the authors of the study said.

Researchers found that each hand could perform the full range of movements. The octopus was favorable with front hands (about 60-40%) above their hind hands. They were more likely to use front hands to investigate, and their back hands move. The Cefalopods of the Dales did not show priorities between their right and left hand.
To understand the movement of animals, researchers at the Florida University and Maritime Biological Laboratory have reviewed the footage of the seabed wild octopus, analyzing them in a frame as a football coach can ruin a difficult game.
The researchers first collected videos from 25 wild octopus, filmed in Spain, South Florida, the Cayman Islands and elsewhere from 2007 to 2015. The divers filmed the creatures by exploring or moving through reefs, sea and sandy bottom of the ocean.

Researchers rated each video frame by frame to create a game of specific hand movements such as adhesion, reduction or rolling, as the animal behaved differently, such as standing or moving a rock.
They interrupted how the animals bent, distracted or extended different parts of the individual limb from the base near the head to the tip of each hand.

Every minute of the video took hours to analyze, Burresch said. In general, the researchers catalog 3 907 hand actions that required 6,871 hand deformities.
An animal hand movement inventory could help investigators better understand nerve relationships that allow the octopus to coordinate their hands to work in different combinations and to receive feedback from the environment.

The octopus has a complex and poorly understood nervous system, with nerves that descend each of their eight hands. Each hand soother gives the animals a touch of touch, but also has chemoreceptors that allow them to taste basically when touching.
“If I am an octopus, I use my hands to drive through the surfaces, paste them into holes in the seabed, look at cracks in coral heads or rocky edges and feel there, but mostly delicious to see what’s going on,” said Burresch.
The octopus has a decentralized nervous system that has more neurons in their hands than in the central brain, Burresch said.
“We all start preparing different parts of a puzzle that explains: How is this strange nervous system that works?”
