“Dr Kubicki said that the amphibian sounds more like an insect than a frog, which may explain how experts missed it during their extensive survey. The frog also measures just one inch (2.5cm) long, making it relatively difficult to spot among the foliage in the west forests and rainforests of the Caribbean foothills of Costa Rica where it was discovered at elevations of between 1,312 ft to 2,624 ft (400-800 m),” according to The Daily Mail.
