Hylidae

**Hylidae** is a family of tree frogs. Some of the Hylids are -aquatic, and others are  frogs.

## Characteristics 
Most hylids have forward-facing eyes that gives them  vision. These hylids are  species, meaning they live in trees. Non-arboreal species do not have any of these advantages. The *Cyclorana* species are burrowing frogs. They spend most of their time underground. Hylids will eat insects and other invertebrates. Larger species can eat small vertebrates.

Hylids lay their eggs in ponds. Some lay their eggs in puddles that in holes inside trees. Others lay their eggs on plants, if water is near. The tadpoles will drop from the plants and into the pond when they hatch. In South America, female hylids carry the eggs on their backs until they hatch.

## Species 
The European tree frog (*Hyla arborea*) lives in middle and Southern Europe. They can also be found in Asia and North Africa. These species are noisy during rainstorms. Many Hylidae live in North America, for example *Hyla versicolor* (Grey Tree Frog) and *Hyla cinerea* (American Green Tree Frog). The spring peeper (*Pseudacris crucifer*) can also be found in the eastern United States. The spring peeper makes loud noises during the spring and summer.

The word "tree frog" is a popular term for many Hylidae. For example, *Hyla versicolor* is the name of the changeable tree frog, *Trachycephalus lichenatus* is the name of the lichened tree frog, and *Trachycephalus marmoratus* is the marbled tree frog. However, the name "tree frog" is not  to this family. "Tree frog" is used more often for many species in Rhacophoridae.
