As the golden frog starts to mature, its skin tone is made up of a light green, yellow, or orange tone with an added stripe pattern that covers the shape of the frog’s body.

Surprisingly as they enter adulthood, the coloration of the skin tone will change to a single dark color, and their unique pattern markings will disappear.

Because their skin releases an alkaloid poison, it is known to cause muscle paralysis, making them deadly and dangerous. These frogs were used by native tribesmen to coat their arrow blowpipes with the frog’s lethal poison.

This made hunting easier for the tribe members as the poison assisted them with catching and paralyzing wildlife. These frogs like to stay close to the ground and prey on species such as

The poison secreted when they feel threatened is extremely toxic, especially when coming into contact with your skin. The consequences of touching the dying poison frog will cause swelling and muscular paralysis will set in.
