CLOWN TREE FROG
WHAT IS IT? Two new species of clown tree frog, with variable splodges of bright colours, can be tricky to identify in the field because some individuals can look more like members of different species than their own. To make it trickier still, they change colour at night. Their calls reveal their true identity.
WHERE IS IT? Surveys of the clown frogs in South America revealed that what were thought to be two species are comprised of at least five. The two that have been formally described so far are from Bolivia and Peru respectively.
