The blue-sided leaf frog (Agalychnis annae) is a species of tree frog in the family Phyllomedusidae native to the tropical rainforests of Central America. It is known only from the Central Valley of Costa Rica, on the slopes of the Cordillera de Talamanca, the Cordillera de Tilarán and the Cordillera Central, at altitudes between 600 and 1,650 m (2,000 and 5,400 ft). The total extent of its range is estimated to be around 16,000 km² (6,178 sq mi), and the International Union for Conservation of Nature has listed it as a vulnerable species. This photograph of a blue-sided leaf frog was captured in Heredia Province, Costa Rica, and was focus-stacked from two separate images.Photograph credit: Charles James Sharp
