He then transferred each colony to a tangle of chicken wire and transplanted the nests into various locations in Tennessee, where the spiders rapidly abandoned the wire to weave treetop webs. In the case of the social spiders, even though group and individual selection may be going in the same direction, group level is stronger, Nonacs said. The sperm receptacles (spermathecae) are globular. The strategy works a bit like a pulley system because the spiders take advantage of the energy in the stretched silk to do some of the lifting for them. A new study reveals the half dollar size animals are able to nab prey 50 times their weight by skillfully manipulating the threads of their webs..
