The average lifespan of a frog is 6 to 8 years. The exact length of time depends on the species of frog.
There are more than 4,700 species of frog around the world as of 2014, with less than 100 species native to the United States. These amphibians are found in every country excluding Antarctica since they cannot live in the harsh weather conditions the continent is subject to.
The majority of frogs are born in water as tadpoles, but a few species give birth to fully developed frogs. When breeding season arrives, frogs often gather at ponds or other bodies of water, and some even return to the place where they developed. After breeding, the female lays clumps of eggs that develop into tadpoles or spawns. Almost immediately, the tadpoles or young spawns are left to fend for themselves. After approximately 12 weeks, they mature into fully developed frogs and at 3 years, they reach sexual maturity and can reproduce. However, only approximately five out of every 2,000 tadpoles or spawns reach adulthood due to predators and other natural causes.
Frogs are nocturnal creatures that feed on small insects. Their diet consists of flies, grubs and earthworms.
