On a Monday in February 2013, Carlos Pages pored over paperwork that accompanied a huge shipment of animals that had just arrived at Miami International Airport on a flight from Paraguay. The crates and boxes contained a wide assortment of species—some 3,500 toads, frogs, tarantulas and snakes. Although the animals arrived in pretty good shape and everything looked okay on paper, something wasn’t quite right, remembers Pages, a U.S. Fish and Wildlife Service (FWS) inspector. Then an email tip came in, informing him that the documents were forged. “Counterparts in Paraguay verified that the permits were fraudulent, and we seized the animals,” he says. Eleven days later, the animals were loaded back on a plane, headed home. En route 204 of them perished. Back in Paraguay, the survivors were examined, quarantined, and the healthy ones were ultimately released back into the wild.
