Facts about this animal

A nocturnal, fairly large frog, attaining sizes up to 8 cm. It is dark brown, with light grey or white banding, patches and points (or light grey with dark brown banding). The belly is also very light grey, with a blue touch at the flancs. Their skin has a very granular or bumpy texture. The feet with their pads are also brown with a blueish sheen. Due to their very large vocal sac the males are capable of producing extremely loud calls.

 

There is no fixed reproduction period. The females lay about 2.000 eggs in water bodies in leaves or similar water bodies in the trees The tadpoples hatch already after one day. After only three further weeks metamorphiosis is completed. Adults will consume almost any type of small arthropod they can overpower and swallow.

Distribution

 


Distribution
Range Bolivia; Brazil; Colombia; Ecuador; French Guiana; Peru; Suriname; Venezuela; possibly Guyana
Habitat This frog inhabits the canopy of tropical primary rainforest, from 0–450 m, where it breeds in tree cavities and may seldom, if ever, descend to the ground.
Wild population Although rarely recorded, probably because of its arboreal habits, considering the wide distribution a large population is presumed. Local populations however are no doubt impacted by forest conversion, clear cutting, selective logging, and human settlement. However, overall this species seems not to be significantly threatened.
Zoo population Recently, thanks to successful captive breeding programs, the Amazon milk frog has become relatively common in collections.

Why do zoos keep this animal

Neotropical frogs are threatened by habitat distruction, disease and other factors. Zoos and aquariums keeping these species want to build up reserve populations and to raise awareness of the global amphibian crisis. Several zoos have also linked their ex situ activities with involvement in in situ conservation.
