Species Identity

Allobates talamancae is a small non-toxic frog.

Snout-Vent Length

Males measure 17 to 24 mm (0.67 to 0.94 inches) in snout–vent length, while females measure 16 to 25 mm (0.63 to 0.98 inches).

Habitat Types

This species occurs in a range of very humid lowland and premontane habitats, including secondary growth, plantations, and swampy areas within primary forest.

Habitat Preferences

It is not found in open areas, and usually occurs close to streams.

Elevational Range

It can be found at elevations up to 800 m (2,600 ft) above sea level, and up to 970 m (3,180 ft) in Colombia.

Diet Composition

Its diet is made up of small arthropods.

Group Behavior

Adult Allobates talamancae aggregate into small groups, a behavior that is likely an anti-predator adaptation.

Threats

Although the species is common, its survival is threatened by habitat loss, the introduction of non-native predatory fish, and pollution.

Oviposition Site

For reproduction, Allobates talamancae lays its eggs in leaf litter.

Tadpole Development

After hatching, both parents carry the tadpoles to streams, where the tadpoles finish their development in small water-filled depressions.
