White's tree frog has pads under each toe and these pads produce a sticky substance called mucus. The sticky mucus helps the frog grip wet leaves and other slimy surfaces. These tree frogs can even climb slippery tree trunks.
Redwoods/Treetop Ecology
The tallest forests on Earth are the redwoods of northern California. Did you know that they depend on Fog? We're studing how these trees work, and we're learning new stuff all the time! For instance, tiny (250 microns) aquatic crustaceans (cousins of lobsters and crabs), which crawled straight up the trunks of redwoods are thriving in mats of moss and organic debris some 65 meters above the ground in the forest canopy. People used to think that they only lived at the bottoms of streams! The redwoods are disappearing, so Global Forest scientists are figuring out ways to protect them.
