Red Eyed Tree Frog....

A tree frog is any frog that spends a major portion of its lifespan in trees.Two lineages of frogs among the Neobatrachia have given rise to tree frogs even though they are not closely related to each other. Many millions of years of convergent evolution, resulting in almost identical habitats and ecologies between the two families, have resulted in species that strongly resemble one another. In fact, they are so similar as regards their ecological niches that where one group occurs, the other is almost always absent.

Before the dinosaurs!

Their present-day distribution indicates that the last common ancestor of the two tree frog groups lived long before the extinction of the dinosaurs! While some reach 10 cm (4 in) or more, they are hardly in the same size class as "grass frogs". Typical for "tree frogs" are the well-developed discs at the finger and toe tips; the fingers and toes themselves as well as the limbs tend to be rather long, resulting in a superior grasping ability.

Stick at it!

The genus Chiromantis of the Rhacophoridae is most extreme in this respect: it can oppose two fingers to the other two, resulting in a vice-like grip.(source Wikipedia)

 

Why tree frogs and Interfire? Because we stick to a problem until it's solved.
