Ji@nBing Posted October 22, 2009 Share Posted October 22, 2009 Yesterday researchers announced the discovery of the largest web-spinning spider in the world. Nephila komaci, which spins meter-wide webs, is 40 mm long. But males of the species (pictured clinging to the underside of the female) are only 9 mm. The spider was discovered in South Africa, and a group of researchers officially described the species in a paper published in PLoS One yesterday evening. Spiders in the Nephilia family all exhibit what's called extreme sexual size dimorphism - in other words, the females are a lot larger than the males, and usually eat the males after mating with them. You can see from these images that the males of N. komaci really are so small compared to the females that they could be mistaken for a post-coital snack. The researchers also analyzed the evolution of these spiders, and concluded that what we're seeing is a tendency towards female gigantism rather than male dwarfism. Because the female spiders survive better the larger they get, they have evolved to be huge. The males, on the other hand, wind up passing along their sperm to the next generation if they mature early (i.e. when they are smaller) and can climb really well. And thus, you get tiny males and giant females. Link Dear god, I'm going to have nightmares about this tonight. It just shouldn't be!!!! Link to comment Share on other sites More sharing options...

Ji@nBing Posted October 22, 2009 Author Share Posted October 22, 2009 I've realized I just don't like creatures with thoraxes. Spiders, ants, whatever it may be, if it's got a thorax, I don't want anything to do with it!!! Link to comment Share on other sites More sharing options...

LightIdea Posted October 22, 2009 Share Posted October 22, 2009 Spiders don't have thoraxes. Uhhh... yes they do. http://www.mcwdn.org/Animals/Spiders.html They are like the other arthropods in that they have an outside skeleton made of chitin, they have jointed appendages and the three body regions of the head, thorax and abdomen.
