Economic Importance for Humans: Negative
Scientists believe that the skin toxins of Phyllobates bicolor are so toxic that .0000004 ounces may be enough to kill a human being. Toxins from these frogs work quickly, attacking the nerves and muscles. Nerve cells can no longer transmit impulses and muscle cells remain in an activated, contracted state. The result is death by respiratory or muscular paralysis (Badger et al, 1995).
