Strawberry Poison-dart Frog, Isla Bastimentos

The Bastimentos red morph, with its vivid scarlet body and black spots, is one of dozens of strikingly different colour forms this species takes across the Bocas del Toro archipelago — making the islands a living laboratory for studying rapid colour evolution. ...
