The Brazil-nut poison frog (Adelphobates castaneoticus) is a species of

endemic to the state of Pará in Brazil.[4] The frog is believed to have received its common name from the fact that its tadpoles sometimes develop in the hard capsules of the Brazil nut tree, which are common in its range. The nuts fall to the forest floor where they are broken open by agoutis and other animals seeking the seeds, and empty husks fill with water.[5]

Description

The Brazil-nut poison frog is a very small frog with a snout-to-vent length of 18 to 23 mm (0.7 to 0.9 in); females are usually larger than males. The

calf is only visible from below.[5]

Distribution

The Brazil-nut poison frog is endemic to the rainforest of central Brazil. It is known from several localities in the state of

leaf litter on the forest floor and sometimes climbs into low vegetation.[5]

Biology

The Brazil-nut poison frog is diurnal and feeds on ants, termites and other small invertebrates.[7] The eggs are laid on the ground where they are guarded by the male. When they hatch, it carries the tadpoles to temporary pools such as water holes in trees and stumps, and water-filled empty nut cases on the forest floor.[5] Here the tadpoles develop rapidly, devouring mosquito larvae, smaller tadpoles, and other creatures that share these ephemeral pools, as well as suitably-sized plant material. This frog may become sexually mature in five to seven months.[5]

Status

The Brazil-nut poison frog is common within its range and the population trend seems stable, although data on its conservation status is somehow insufficient.

least concern".[7] The main threats it faces are logging, habitat destruction, wildfire and collection of animals to be sold as pets on an international market. There are some conservation areas within its range.[1][5]
