MILKY TREE-FROG Trachycephalus venulosus
A large and distinctive, if variable, tree-frog. This is the only tree-frog to emit a milky substance from the skin when molested, the "milk" drying to form a gooey "latex" which acts as a form of defence against predators - inhale too much of it and you may find yourself suffering some ill effects. The call is surprisingly loud, and was likened to a "short-circuiting car-horn" by one herpetologist!
