Both frogs and toads need water to survive.  Both species lay their eggs in water and their eggs hatch into tadpoles.  Tadpoles cannot survive in open air.

Egg-cetera: Both frogs and toads lay gelatin-like eggs in water that cling to aquatic vegetation, rocks or detritus; frog eggs are in clusters and toad eggs are in strings.

Frogs typically lay their eggs in water, but a few of the species will lay their eggs on land, bypassing the tadpole stage. Aquatic larvae, called tadpoles, have tails and internal gills.

Frogs and toads in the U.S. have some of the most eclectic diets imaginable. All adults are carnivorous, whereas tadpoles — the larval aquatic stage of development — are generally herbivorous.

Most everyone recognizes frogs. Frogs, like salamanders and newts, are amphibians. Unlike salamanders, they have made a major evolutionary detour from the body plan of their ancient ancestors. The ...

Frogs typically live closer to aquatic habitats while toads are often found in dryer terrestrial habitats. If you come across frog or toad eggs floating around, you can tell which is which based ...

“Frogs, on the other hand, lay their eggs in masses,” Arizona wildlife officials said. “So seeing a string like this immediately tells you you’re looking at toad eggs.” ...

The frogs and toads of our area sing when waters in their selected breeding ponds and wetlands reach just the right temperature. Depending on the species, that temperature varies.

Still others, though, are much easier to distinguish. There is the wood frog’s distinct, throaty chuckle, for example. And the American toad’s shrill whistle.

3. Like many salamanders that begin their life as eggs and larvae in the water, most North American frogs and toads spend their adult life on land, making them some of the best biological ...
