Also known as the "Brazil-nut Poison Frog" or "castas", Adelphobates castaneoticus is a small, terrestrial species endemic to Brazil. The IUCN classifies Adelphobates castaneoticus as Least Concern (LC) based on the most recent assessment for the species in 2021.[1]
Description[edit | edit source]
Adult Adelphobates castaneoticus are between 0.7 in. and 0.9 in. (18-23 mm) with a black body, accented by small stripes or white spots on the back, and yellow or orange bright spots on the front and back of the limbs. Like other poison frogs, Adelphobates castaneoticus utilizes water-filled parts of plants on or near the forest floor for tadpole deposition. However, this species seems to also take advantage of fallen rain-filled fruit capsules of the Brazil nut tree as well.[2]
Geographical Distribution[edit | edit source]
While the full range of Adelphobates castaneoticus is not well documented, the species is known to inhabit the lowland rainforests of Pará, Brazil. [2]

Reproduction[edit | edit source]
Male Adelphobates castaneoticus will call near a laying site to attract a female. The female will deposit eggs in fruit husks (such as those of the Brazil nut tree), or axils of bromeliads and other water-filled plants. The tadpoles are transported by males to other axils where they feed on mosquito larvae, on tadpoles of other frogs, or cannibalistically on conspecific tadpoles.[3]
Diet[edit | edit source]
Little is known about the wild diet of Adelphobates castaneoticus, though notably, tadpoles have been observed attacking and consuming tadpoles of other species of frogs, as well as cannibalistically feeding on other castaneoticus tadpoles.[3]
Threats[edit | edit source]
- Agriculture and aquaculture
- Natural system modifications
- Hunting & trapping
- Logging and wood harvesting
Conservation[edit | edit source]
The wild distribution of Adelphobates castaneoticus is not well understood. The species is prolific and well-established in captivity, particularly in the European Union.
