🐸 Phyllobates terribilis

Today we're talking about the Phyllobates terribilis , better known as the golden poison dart frog : small, colorful... and incredibly lethal.

📌 Technical Data Sheet

Scientific name: Phyllobates terribleis
Common name: Golden Poison Dart Frog
Class: Amphibians
Order: Anura
Family: Dendrobatidae

📍 Habitat and Distribution

It lives exclusively in the rainforest of Colombia's Pacific coast , in warm, humid, and vegetated environments. It prefers low-lying areas, close to the forest floor.

📏 Dimensions

• Length: 4–5.5 cm
• Weight: about 1 gram

Despite its small size, it is considered the most venomous animal in the world.

☠️ Poison and Danger

Its skin secretes a very potent neurotoxin called batrachotoxin .

• It can cause muscle paralysis and cardiac arrest .
• A single frog contains enough venom to kill up to 20 adult humans .
• The venom works by interfering with sodium channels in the nervous system.

The indigenous people of Colombia used its venom to poison blowpipe arrows (hence the name “arrow frog”).

🎨 Colors (Aposematic Coloration)

Despite the name "golden", it can come in different variations:

• 💛 Bright yellow
• 💚 Mint green
• 🧡 Orange

These bright colors serve as a warning to predators : “Don't eat me, I'm poisonous!”

🍽️ Nutrition

It feeds mainly on:

• Ants
• Termites
• Small insects

Interestingly, its venom likely comes from toxins present in the insects it feeds on. In captivity, it loses much of its toxicity.

🧬 Curiosity

• In captivity it can live up to 10–15 years .
• It is active during the day (diurnal species).
• It is not aggressive: the danger is only in contact with the skin.

🌿 Conservation Status

It is threatened by deforestation and the destruction of its natural habitat.

The Phyllobates terribilis reminds us how nature can be both fascinating and powerful: a few centimetres of bright colour contain one of the most extraordinary defences in the animal kingdom.
