New study confirms octopuses have more arms than legs
2008-08-14 21:36:54 (GMT) (Caymanmama.com - Cayman Islands News)Grand Cayman, Cayman Islands (CaymanMama.com) — The Cayman Islands are known for their tropical paradise locale and exotic marine life. Although sting rays are the primary attraction in the Caymans, ever so often, an octopus will show it’s tentacled body and a swarm of photographers will gather to film the spectacle.
According to a recent report by Reuters, the interesting species with eight legs has now been demystified. On Thursday, a new study published by a chain of commercial aquariums said that the octopus has six “arm” and two “legs” to propel itself through the water. The funny looking creature is renowned to be on of the world’s most intelligent invertebrates and are able to be completely independent and full-functioning using their sucker-covered tentacles.
Sea Life aquariums said that with the assistance of approximately 2,000 observations by interested visitors, an experienced set of aquatic specialist teams conducted a study indicating that the octopus favors its first three pairs of tentacles to grab and use sea objects.
Sea Life biologist Oliver Walenciak said, “One can assume that the front six tentacles have the function of arms, and that the back two take over the function of legs. People have always assumed that octopuses coordinate their … gripping behavior through visual data. That seems to be true. When one eye is weak, another side of arms is favored.”
Unlike humans, octopuses are not primarily right or left “handed”. However, those octopuses that did favor one side versus the other were observed to suffer from vision problems on the side they favored less. The benefit of the study, among others, is that knowing this information will allow marine caretakers to provide specialized medical care for ill octopuses by allowing them to be fed from the correct side.
