Armed with headlamps and flashlights, a group of researchers set out into the darkness in Bolivia on the hunt for the native wildlife. They were on a mission to catalog the reptiles and amphibians that call the central South American country home from the dense rainforests to the high plateaus and snow-capped mountains. The researchers “traversed the area on foot” and collected animals by “hooks, tongs or by hand,” according to a study published Sept. 11 in the peer-reviewed journal Check List.
