Conservationists are hoping to strengthen regulations at a wildlife trade conference on birds, reptiles and other animals that are seeing their numbers decline due to the exotic pet trade. The two-week meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora is running through Friday in Samarkand, Uzbekistan. There are proposals to tighten regulations or outlaw the trade of several species including iguanas from the Galapagos Islands, more than a dozen species of Latin America tarantulas and a strange-looking turtle from Africa. Experts say the market is fueled by the internet and social media.
