Burmeister's Tree Frog

B. prasina is a medium sized frog measuring 4 to 5 cm long. It is usually light brown with dark scattered spots across its back, but can also be brown, yellow or green. The belly of B. prasina is a lighter shade than the back. B. prasina has also been referred to as the rattle-voiced tree frog because of its call, which follows a rattle-like beat. The frogs typically croak when in low vegetation at the edge of water, although now appear in artificial garden lakes and lawns. The frog is generally nocturnal, sometimes appearing at dusk.

B. prasina is limited to the elevated regions of southeastern Brazil. However, it does live in a wide variety of habitats including lakes/ponds, fields, pastures, muddy soils, and forests. They can be found both on the ground or in trees. In forests, it usually inhabits open areas or the edges. The forests are always very close to water, and are either riparian or gallery forests.

Tadpoles of B. prasina have fewer labial tooth rows than other tree frog species. Having fewer labial tooth rows may make feeding from three-dimensionally irregularly shaped surfaces, like algae, more efficient. Adult B. prasina feed on small insects and other arthropods. It has been suggested that the differences in secretions between male and female B. prasina are due to differences in their diet or how they spend their time. However, this explanation seems unlikely as differences in diet occur during early infancy.
