10 Poisonous Frogs In The World You Should Know About
Frogs are amphibians belonging to the order Anura, which means "without a tail." They are known for their unique life cycle, including metamorphosis from tadpoles to adults. Frogs have been around for millions of years and are found on every continent except Antarctica. Certainly! Here are some poisonous frog species known for their toxic skin secretions.
10. Golden Poison Dart Frog
The Golden Poison Dart Frog (Phyllobates terribilis) is a small, brightly colored amphibian native to the rainforests of western Colombia. It is widely regarded as one of the most toxic animals on Earth. The frog's vibrant golden-orange coloration serves as a warning to potential predators, indicating its extreme toxicity.
The skin secretions of the Golden Poison Dart Frog contain a potent neurotoxin called batrachotoxin, which can be lethal even in tiny amounts. Indigenous people in Colombia have historically used these toxins to poison the tips of blow darts for hunting, hence the frog's name.
