Jumping Spiders are fascinating creatures. They are not the typical representatives of the arachnid family, and for many reasons. One reason, and perhaps the most well known reason among spider enthusiasts, is their superior eyesight relative to other arachnids. Their eyesight is so acute that it is on par with vertebrats. But they are also unique in that they are surprisingly aggressive for their size. For example the Jumping Spider considers just about any other spider fair game as potential prey. Jumping Spiders serve as predators to other predators. In other words, the jumping spider is so advanced as a spider that it can make a meal out of spiders that are the biggest and most feared killers in the spider world, and this is despite the jumping spiders small size.
It is supposed by researchers that if a Jumping Spider is able to resort to extra cunning in order to attack and eat even bigger spiders, then the jumping spider must be, as a result of a yet to be discovered adaptation, more intelligent than the vast majority of other spiders. So researchers decided to test this hypothesis by constructing a complicated trail that would end in bug parts and other desirable types of food that all spiders can agree are pretty tasty.
The researchers set loose a variety of different arachnids in order to see if any of them were capable of the abstract thought that was necessary to find the food. Of course all the spiders failed to find the end of the trail where the food was waiting for them, except, of course, for the Jumping Spiders. The Jumping Spider was the only spider capable of changing its directory to the path that led to the food. As a result of the experiment researchers are convinced that a Jumping Spider’s brain, despite being as small as a sesame seed, is advanced enough to reason its way to the correct food source in spite of the many tricks that were laid upon its path.
Do you believe that there is a clear correlation between brain size and mental sophistication?
