Some species live in the areas of the Amazon and Orinoco rivers.

Initially, they lived only in the northwestern part of South America, after which they significantly expanded their habitat. Glass frogs nest on trees in tropical and semi-deciduous forests. Closer to the water, they move only during the breeding season.

The skin on the abdomen of such a frog is translucent and through it you can see the internal organs of the frog - the liver, heart, gastrointestinal tract, and sometimes even eggs in females.
