Alabama's Frogs and Toads | ||
Frogs, toads, and salamanders make up the group “amphibia”.
Amphibians with no tails are called “anurans” – this includes frogs and toads. |
|
|
Alabama is home to 30 species of anurans – 4 toads and 26 frogs. | ||

All toads are frogs, but not all frogs are toads! | ||||
There are some easy-to-spot differences between frogs and toads:
1. Frogs have smooth, moist skin and toads have bumpy or warty, dry skin.
2. Frogs have longer back legs than toads.
3. Because of the difference in leg length, frogs leap long distances while
toads hop short distances. 4. Frogs lay their eggs in clusters while toads lay their eggs in chains. 5. Frogs have teeth in the upper jaw while toads to not have any teeth. 6. Frogs typically live in wetter environments while toads typically live in drier environments. |

Life Cycle | ||
Frogs and toads both live part of their life in water and part on land.
Baby frogs do not look like adult frogs. They undergo metamorphosis (a physical change) as they grow. |
||
Step 1: | They begin life as eggs in water. |

|
Step 2:
|
They hatch from the eggs and spend time as an aquatic tadpole.
They look more like a fish than a frog at this point. They have no legs and a tail, their mouthparts are for eating algae, and they have gills instead of lungs. |
|
Step 3: | The tadpole begins changing – legs grow, mouthparts shift, tail shrinks, and finally gills become lungs. | |
Step 4: | The tadpole moves onto land with all four legs and lungs and eats bugs.
At first, it will still have a short tail. At this point it is called a froglet. |
|
Step 5: | The tail is fully absorbed and it is now an adult frog that will reproduce and lay eggs to start the process all over again. | |
Habitat Needs | ||
Food: | ||
As tadpoles:
Herbivorous (eat only plants)
Aquatic (live in water)
|
As adults:
Carnivorous (eat only meat)
Terrestrial (live on land)
|

The water in and vegetation around your pond will provide food directly for the frogs and toads as herbivorous tadpoles, as well as carnivorous adults by attracting insects. |
||
Water: | ||
Frogs and toads require water for several reasons:
The pond will provide the water needed for frogs and toads throughout their whole lives.
The aquatic plants inside of and around the pond will filter and aerate (bring in air) the water.
|
||
Shelter: |
Frog and Toad Habitat |
|
Frogs and toads have several options for shelter in your habitat:
|
||
Place to Raise Young: | ||
Frogs and toads will lay their eggs in your pond.
They do not protect or stay with the eggs once they are laid, and tadpoles hatch from the eggs ready to start life on their own. |
Interesting Facts | ||
#1:
|
Frogs and toads have unique, specialized feet for their specific habitats. | |
Tree frogs have toe pads that help them stick to surfaces while they are climbing.
Species of frogs, like bullfrogs, that live in water have webbed hind feet to help them swim.
Spadefoots, a type of frog that burrows into soil and lives there most of the year, have hard spots called “spades” on their hind feet that help them dig.

#2:
|
Frogs absorb water and even breathe through their skin.
This is why it’s important that you don’t hold them in your hands for a long time (they’ll dry out) or hold them if you have chemicals on your hands like bug spray or lotion. |
|
#3:
|
Alabama has the third highest number of amphibian
(frogs, toads & salamanders) and reptile (snakes, turtles, lizards, and alligators) species out of all 50 states in the U.S.
This means we have more reptile and amphibian diversity than all but two other states.
