Tree frog

Arguably the cutest of all amphibians, tree frogs are ideally adapted to life in the canopy. Though there are many different species of tree frog, most of them share some common traits. For instance, they're typically more slender than their pudgy, land-based brethren. They're also usually much smaller, which makes them all the more adorable. Long fingers and toes help them to grasp limbs, and the ends of their digits are often disc-shaped for added suction capabilities.

Unfortunately, tree frogs — like most of the world's amphibians — are in steep decline worldwide due to chytridiomycosis, a deadly fungal disease.
