LA PAZ: A rare species of frog native to the eastern slopes of the Bolivian Andes has been spotted in the South American country for the first time in 18 years, the investigation team that made the discovery told Agence France-Presse. The Bolivian Cochran frog is notable for its transparent belly, leading to its nickname, the “glass frog.” “The rediscovery of this species fills us with a ray of hope for the future of the glass frogs — one of the most charismatic amphibians in the world — but also for other species,” said investigation team members Rodrigo Aguayo and Oliver Quinteros.AFP
