The golden frog secretes the alkaloid toxin batrachotoxin, which is of interest to medical researchers who are trying to develop muscle relaxants, heart stimulants and anesthetics from the toxin. Poison frogs are known for their beautiful colors, and amphibians that have toxic skin secretions tend to have bright warning colors or patterns.
The most poisonous of these frogs, the golden poison frog (Phyllobates terribilis), has enough toxin on average to kill ten to twenty men or about ten thousand mice.  Most other dendrobatids, while colorful and toxic enough to discourage predation, pose far less risk to humans or other large animals.
The National Museum of American History collects artifacts of all kinds—from gowns to locomotives—to preserve for the American people an enduring record of their past. We have more than 1.7 million objects and 22,000 linear feet of archival documents in our collection.
These frogs are considered one of Earth's most toxic, or poisonous, species. For example, the golden poison dart frog has enough poison to kill 20,000 mice. With a range of bright colors—yellows, oranges, reds, greens, blues—they aren't just big show-offs either. Those colorful designs tell potential predators, I'm toxic. Don't eat me. Scientists think that poison dart frogs get their.
