Researchers find octopus with 6 arms and 2 legsAugust 14th, 2008 - 1:56 pm ICT by Bupha Ravirot
Researchers in London have been studying A giant Pacific octopus called Mavis, to prove that octopuses do not really eight-legged denizens of the deep, as popularly assumed.
Mavis, who lives in a tank at Weymouth Sea Life Centre, actually has six arms and two legs. How?
The researchers observed Mavis behaviour and compiled data from 2,000 observations of octopuses playing with toys such as the Rubik’s Cube indicate that octopuses have six ‘arms’ and two ‘legs’. It had been believed that the back four tentacles were used for propulsion and the front four for manipulation. But researchers have found that they use the rearmost two tentacles, their legs, to get around over rocks and the seabed, leaving the remaining six arms for eating. They use their third pair of arms to help them get out of a tangle.
The research have also conducted at 20 centres across Europe, tend to establish whether octopuses favoured one side over the other or were multidextrous.
“We identified seven octopuses that genuinely do prefer one side over the other, possibly because of some weakness in the other eye” says Claire Little from the Weymouth Sea Life Centre.
The studied also discovered that octopuses are considered to be intelligence animal as they solved the given tasks by self learning.
“octopuses are among the most intelligent of marine creatures and can learn to open jam jars and manipulate small objects such as the Rubik’s Cube – although, so far as is known, none has yet succeeded in solving the puzzle” noted The Times.
