Analyze the amphibian's features. Baby frogs no longer have gills; Instead, they have lungs for breathing. Frogs have a squat body, four legs, smooth skin, two giant eyes and unique feet. They do not have visible ears. The hind legs of frogs are generally much bigger than the front pair. Frogs can be different colors, such as camouflage green (tree frog), bright red (poison dart variety) and even spotted (African reed frog). They absorb water through their moist skin and live their lives in the water and on land.
Study the feet. Baby frogs will have evolved from tadpoles, and they should no longer have a tail. Front feet have four fingers, while hind feet have 5 toes. Their feet should be fully transformed to that of their unique species. Webbed feet show evidence of strong species swimming ability, suction-cups display tree-climbing skills and rough spurs on hind feet assist ground burrowers.
Observe the amphibian's behavior. Baby frogs--like that of their mature counterparts--are known to leap great distances (as far as twenty times their body length). They are generally most active at night time. Frogs do not drink water, but they can be spotted sitting in water or resting on moist riverbanks, absorbing moisture through their slimy skins.
Watch them eat. A baby frog will catch its prey with a long, sticky tongue, quickly retracting it back into its mouth, swallowing it whole. Many frog species eat worms, spiders and centipedes. Frogs benefit society by helping keep insect populations under control.
Listen to the frog communicate. If the observed amphibian is a baby frog, it will make a variety of sounds, such as croaks and "ribbit" sounds. Male frogs have been known to sing. Frog communication is generally high during mating season.
Consider the habitat. Baby frogs, having evolved from a tadpole, can now live life on both land or water. Depending on the species variety, frogs can live in warm, tropical climates and even cold, polar regions. Most frogs live close to a water source, but they can live in burrowed passages beneath the ground and high up in trees.
Watch for lurking predators. Many creatures feed on baby frogs--including turtles, snakes, bats and fish. Many frog species will hide to stay safe, while others puff themselves up or even play dead as a defensive mechanism.
How to Identify Baby Frogs
A highly-adaptable amphibian, the frog can live in diverse climates and habitats, from high-elevation mountain ranges to burrowed passages beneath the ground. Frogs have a unique life cycle. They hatch from eggs and begin life as an aquatic tadpole; the tadpoles undergo a metamorphosis that transforms their shapes into adult frogs. A "baby" frog is identifiable through the metamorphosis stage, as the frog has taken on mature species attributes (has legs, but no tail), but is not yet full-grown in size. Identifying a baby frog of any variety is easy to accomplish, requiring only a basic understanding of the frog species.
