My key takeaways: * An analysis of online sales listings turned up more than 1,200 species of spiders, scorpions and other arachnids; just 2 percent of them are subject to international trade regulations, the researchers report * Fish and Wildlife Service trade database included only 267 arachnid species, the scientists found * The Convention on International Trade in Endangered Species of Wild Fauna and Flora, or CITES, which regulates the international trade of a variety of plant and animal species, had just 30 species in its trade database * Nearly 200 of the species that have been discovered since 2000 are already being traded; dozens were available within a year or two of first being described, the researchers found * In another recent study, researchers at Cornell University found multiple species of endangered tarantulas being sold online * “Arachnids are being massively traded,” Dr. * Hughes said. * “And it seems to be going completely under the radar.”
