The World's Five Most Poisonous Frogs: Do You Know Them?

In nature, some frogs are famous for their potent toxicity. They are not only part of the ecosystem but also the subject of scientific research on toxins. Today, let's learn about the world's five most poisonous frogs.

1. Golden Poison Dart Frog (Phyllobates terribilis)
   Habitat: Colombia
   Toxicity: The golden poison dart frog is the most poisonous vertebrate known. Its skin secretes toxins that can kill up to 20 people or two elephants.
   Toxin: Extremely potent alkaloids, such as batrachotoxins.
2. Black-legged Poison Dart Frog (Phyllobates bicolor)
   Habitat: Colombia and Panama
   Toxicity: Second only to the golden poison dart frog.
   Toxin: Its skin secretes batrachotoxins.
3. Blue Poison Dart Frog (Dendrobates azureus)
   Habitat: South America, mainly Suriname and Brazil
   Toxicity: Highly toxic, but less so than the golden poison dart frog.
   Toxin: Its skin secretes alkaloids.
4. Green and Black Poison Dart Frog (Dendrobates auratus)
   Habitat: Central America, mainly Nicaragua, Costa Rica, and Panama
   Toxicity: Highly toxic, but relatively lower.
   Toxin: Its skin secretes batrachotoxins.
5. Kokoe Poison Dart Frog (Phyllobates aurotaenia)
   Habitat: Colombia
   Toxicity: Highly toxic but less than the golden and black-legged poison dart frogs.
   Toxin: Its skin secretes batrachotoxins.
   The toxicity of these frogs is primarily transmitted through the toxins secreted by their skin. They usually do not attack humans but can cause severe poisoning or even death if accidentally touched or ingested. In nature, their toxicity is mainly used for defense against predators.
