How does the posion dark frog kill?

Poison dart frogs, particularly those from the genus Phyllobates, produce potent toxins called batrachotoxins in their skin. These toxins can cause paralysis or cardiac arrest in predators, making the frogs highly toxic. The frogs themselves acquire these toxins from their diet in the wild, consuming certain insects. When indigenous people used these frogs to poison the tips of their blow darts, they effectively utilized the frogs' natural defenses for hunting.
