Thank you to Joel Sartore for the licence to use his photo for this oil painting in the header of this page of A pink-sided leaf frog (Agalychnis litodryas) collected near Pilalo, Ecuador.
Joel went to Ecuador to photograph amphibians, primarily frogs back in 2008.
Amphibian species are declining especially rapidly due to a host of issues from chytrid fungus to habitat loss and pollution.
