 | | It is Portia, a member of the Salticidae or jumping spider family, a creature that for 10 years has been the focus of research by R. Stimson Wilcox, a Binghamton biology professor, and his collaborator, New Zealand biologist Robert Jackson. |
 | | Portia is known to use its legs, palps, body movements or various combinations to make vibrations mimicking everything from a trapped insect to an interested suitor on the web of its intended victim. |
 | | Portia, in fact, is such a formidable predator that, in a sort of "evolutionary arms race," some prey spiders have actually "learned" through natural selection to recognize its walk on their web, Wilcox said. |
