Tiny, dainty spiders no bigger than a Tic-Tac probably wont send your blood pressure rising. But the 4-inch-long, red-fanged Sierra Cacachilas wandering spider (Califorctenus cacachilensis), recently named by researchers at the San Diego Natural History Museum and Mexico's Centro de Investigaciones Biológicas del Noroeste, is another story.
The species was first located in 2013 in a mountain range in Baja California Sur, Mexico. Researchers, including field entomologist Jim Berrian, came across evidence of an abnormally big shed exoskeleton in a cave. The eye pattern led them to believe it was potentially part of a group of wandering spiders from the Ctenidae family.
Knowing Ctenidae are nocturnal, the researchers returned to the cave at night, where they spotted a living specimen. The team confirmed it was a previously unidentified species, with the findings published in Zootaxa in March.
The cave-dwelling wandering spider is related to the Brazilian wandering spider, known to be highly venomous. Although researchers havent fully examined the consequences of a bite from the Sierra Cacachilas, informal research indicates it probably wont kill you. I got bit while handling a live specimen of Califorctenus cacachilensis, and Im still alive, Berrian said.

(7,997 posts)I just hope I never encounter one unexpectedly! Maybe some day I will learn to appreciate them more than I fear them.

(58,513 posts)There has never been a recorded human death from its bite. However, P. metallica's bite is considered medically significant, with venom that may cause intense pain, judging from the experience of keepers bitten by other spiders from the genus.[6][7] The vast majority are "dry bites," where no venom is injected into the handler. The mechanical effects of the bite can still be worrisome, as an adults fangs can reach nearly 3/4 of an inch in length. P. metallica can move rapidly and may defend itself when cornered. Venom may produce a heart-rate increase followed by sweating, headache, stinging, cramping, or swelling. Effects can last for up to a week.[8]

(11,686 posts)one crawling on me. When I find spiders in the house I catch them and and let them crawl on me as I put them outside. I have never been bitten by a spider but my friend has a body type that if she sleeps outside spiders will come and munch on her. The bites are like mosquito bites but much larger, more painful, and looks like bruising.
