CharacteristicsEdit

Most hylids has forward-facing eyes that gives them binocular vision. These hylids are arboreal species. Non-aboreal species do not have any of these advantages. The Cyclorana species are burrowing frogs.[1] They spend most of their time underground. Hylids will eat on insects and other invertebrates. Larger species can eat small vertebrates.

Hylids will lay their eggs in ponds. Some will lay their eggs in puddles that are found in the holes of trees. Others will 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 will carry the eggs on her back until they hatch.[1]

SpeciesEdit

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 a rain storm. In North America, there are many species of the Hylidae family. These include Hyla versicolor (Grey Tree Frog) and the Hyla cinerea (American Green Tree Frog). The spring peeper (Pseudacris crucifer) can also be found in Eastern United States. The spring peeper will make loud noises during the spring and summer time.

The word "tree frog" is a popular name for several of the Hylidae. For an example the 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 name of the marbled tree frog. However, the name "tree frog" is not "unique" to this family. The word "tree frog" is used more often for many species of the Rhacophoridae.
