Centrolene is a genus of glass frogs in the family Centrolenidae.

Some species are called "giant glass frogs".

The taxonomical classification of the glass frogs has been problematic.

As a result, some glass frogs show parental care.

Male glass frogs are 19-28 mm long while females measure from 23-32 mm long.

It is not specifically known what the glass frog eats, but it is assumed that they feed on small insects.

There have been more than 100 reported glass frogs throughout Central and South America.

A simple direct shot from a raindrop has been known to kill a glass frog.

Most glass frogs are a lime green color.

For some glass frogs the skin on the stomach area is transparent.
