(Melin, 1941)

Ameerega bassleri, commonly known as the "Pleasing Poison Frog" or simply "bassleri" among hobbyists is a diurnal, semi-arboreal species of poison frog native to mountain forests in the eastern Andes of Peru. [1] Renowned for its bumpy skin and vivid black and light green or blue coloration, it is prolific and a popular species among intermediate poison frog hobbyists.

Description[edit | edit source]

Adult Ameerega bassleri typically measure about 42 mm (1.65 inches) in size.[2] [3]

Their coloration varies geographically but generally includes vibrant combinations of blue, green, and black. Like other Ameerega, its skin is very bumpy.

Locales[edit | edit source]

Geographical Distribution[edit | edit source]

Ameerega bassleri inhabits mountain forests in the eastern Andes of northern and central Peru. It is a highland species, preferring cooler temperatures and higher humidity, and is typically found between 500-1,100m elevation.[5]

Reproduction[edit | edit source]

In the wild, Ameerega bassleri reproduce year round. Like other species of Ameerega, females lay clutches terrestrially on leaf litter, where they are guarded and tended by the male until they hatch. Once tadpoles emerge from their eggs the male transports them to small pools of water or puddles. The average clutch contains about 17 eggs. [5]

Diet[edit | edit source]

Ameerega bassleri feed primarily on small arthropods like ants, mites, and springtails. In captivity they primarily consume wingless or flightless fruit flies.

Calls[edit | edit source]

Male Ameerega bassleri vocalize with short chirping calls to establish territories and attract females.

Conservation[edit | edit source]

Wild populations of Ameerega bassleri are declining. The species is listed as Vulnerable by the IUCN as a result of habitat loss due to coffee plantations, palm plantations, and cattle pastures. [6]
