Can't believe I missed this Halloween posting opportunity...The Florida Department of Agriculture and Consumer Services recently released a Public Service Announcement warning citizens about the Mexican red rump tarantulas (Brachypelma vagans) that have established in that state. The tarantula, native to Central America and Mexico, was first discovered (.pdf) in St. Lucie County over a decade ago, and is thought to have been introduced via the pet trade.
You can view the PSA via this page (wmv format). I couldn't get the link to work but the transcript (.pdf) sounds pretty amusing. Interested readers will also want to check out this response to a proposed tarantula ban in Florida, posted on the American Tarantula Society's website.
