Dyeing Poison Frogアイゾメヤドクガエル
Dendrobates tinctoriusLC— Least Concern
The dyeing poison frog is one of the largest species in the poison dart frog family, native to primary rainforest of the eastern Guiana Shield in South America. Its bold black-and-yellow or blue patterning warns predators of skin toxins that, notably, are not self-produced but sequestered from a diet rich in alkaloid-containing ants and mites—meaning captive-bred frogs raised on standard feeder insects lose their toxicity entirely. Parents carry newly hatched tadpoles on their backs to water, and the species' name references an indigenous tradition of using its toxin to alter the color of parrot feathers.

Species Data
Did You Know?
- Its species name tinctorius means "for dyeing," referencing an indigenous tradition of using the frog's toxin to change the color of green parrot feathers. Source
- The toxin is not self-produced but sequestered from a diet of alkaloid-containing ants and mites, which is why captive-bred individuals raised on standard feeder insects lose their toxicity entirely. Source
- Females lay clutches of 8 to 10 eggs under leaf litter, and once hatched, a parent carries the tadpoles on its back to a suitable water source. Source

FAQ
- Is the dyeing poison frog dangerous to touch?
- Wild individuals carry toxic alkaloids in their skin that can cause numbness and other symptoms on contact, but captive-bred frogs raised on standard feeder insects lose this toxicity because the toxin comes entirely from their wild diet rather than being self-produced. Source
- Why is it called the "dyeing" poison frog?
- Its species name tinctorius means "for dyeing," reflecting an indigenous tradition of using its skin toxin to alter the color of green parrot feathers. Source
- Do dyeing poison frogs care for their young?
- Yes. After eggs laid under leaf litter hatch, a parent carries the tadpoles on its back to a nearby water source where they can continue developing. Source
