Resumen

Oedipina berlini es una salamandra terrestre endémica de los bosques tropicales del Caribe de Costa Rica, su historia natural es poco conocida debido a los pocos registros que se tienen desde su descubrimiento. En este artículo describimos un comportamiento antidepredador de esta especie, que consiste en un salto impulsado únicamente por su cola. Este nuevo método de defensa contra los depredadores nos dice cuán compleja y poco estudiada es la historia natural de las salamandras tropicales. Adicionalmente, reportamos la presencia de esta especie en el Parque Nacional Braulio Carrillo, siendo la quinta ubicación conocida para O. berlini y el punto más al norte de su distribución.
