Based on the available science it appears that the green and black poison dart frog (Dendrobates auratus) is the smartest frog thanks to its ability to create complex mental maps of its environment which requires a high level of awareness of environmental cues and locations.
Archey's frog is the world's most Evolutionarily Distinct and Globally Endangered amphibian species.

Examples of weird amphibians include the Chinese giant salamander, the world's largest amphibian; amphiumas, a group of eel-like salamanders with tiny legs; the African clawed toad, which has bizarre clawed hind feet; the olm, a blind, cave-dwelling salamander; and Wallace's flying frog, which is able to glide with its ...
Most Amphibians are tetrachromats - their retinas contain 4 types of photoreceptors and they are therefore capable of color vision with a broader sensitivity to color than humans.
Some have tiny teeth on their upper jaws and the roof of their mouths while others sport fanglike structures. Some species are completely toothless. And only one frog, out of the more-than 7,000 species, has true teeth on both upper and lower jaws.
There are only 50-1,000 axolotls left in the wild, though there are as many as 1 million in captivity worldwide.

Few frogs approach mammals or birds in terms of intelligence, though many do rival or surpass reptiles, and the most intelligent are thought to come close to the intellectual level of a bird or lower mammal. Wood frogs, Rana sylvatica, have demonstrated a basic capacity to learn.
Eyes positioned atop the head give frogs a field of vision of almost 180 degrees. This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens.
Frogs Can Experience Oxytocin Increases – AKA Happiness
Like oxytocin in humans and other animals, mesotocin in frogs helps these amphibians feel content with their environment and not be stressed.
Most mammalian red blood cells are highly evolved and have lost their nucleus. The nucleated red blood cells illustrated in the phase contrast optical micrograph above were derived from a frog, but are common to all amphibians.
