POISON-DART FROGS mm W U Text and As a bird flashes by photographs by high above him, MARK W. Paulino Hueso lifts MOFFETT the mouth of a long blowgun to his lips and gives a quick puff. The snapping sound of a dart striking bark signals a miss. Hueso's darts are tipped with one of the most potent tox ins known. It is secreted by two-inch long Phyllobates terribilis (right), a frog found only in a small area of lowland rain forest in western Colombia. When one boldly hopped to within inches of my camera, I kept in mind the warning of John Daly, one of the sci entists who discov ered P terribilis: The frog can be lethal even to the touch.
