The lecture is about one colorful frog called dart-poison frog. Actually, its bright color could warn predators that they are poisonous. In the past, hunters used these frogs’ poison at arrows, and now researchers are about to utilize the poison for making heart medicine because it could stimulate body’s nervous system and heart. But it is difficult to acquire the poison from either wild or captive frogs.
