Spiders are small, sometimes less than one millimeter, it has a big brain. So big, the brain to "creep" up to the foot.
Bill Ebenhard of the Smithsonian Tropical Research Institute and professor at the University of Costa Rica, studied nine species of spiders. He found that the smaller the spider, the larger brain size relative tehadap body.
Ebenhard, as described in National Geographic, Monday, 19.12.2011) and then, to explain, in some spiders, the brain can fill 80 percent of the body. In infants spider species Leucauge Mariana, the brain is not only packed the head, but also the body.
Meanwhile, Ebenhard also found in species of Phidippus Clarus oddity. The baby's body spider species were filled by the brain. When mature, it grows digestive organs in the head and chest.
The magnitude of the brain may be disturbing other organ development and other mechanisms in the body of the spider. However, Ebenhard said, so far no studies on it.
Allegedly, a large brain associated with the ability of spider webs. However, because the allegations countered kleptoparasitic spiders that do not have the ability to build the nets turned out to also have large brains. There is no certainty about the consequences of big brains.
Research on spider was published in the journal Arthropod Structure and Development in November 2011 yesterday
