Its poison is one of the most powerful known and can cause paralysis or death. It is so potent that one millionth of an ounce can kill a dog and an amount smaller than a grain of salt can kill a human.
One frog carries enough poison to kill about 100 people. Native hunters use it on the tips of their arrows which is how the frog got its name.
