Dissection 4: Frog

Background Information:

Specimen:
Frog (Amphibia)

Habitat:
Frogs are amphibians, meaning they can live on land as well as in water. They are mainly found in marsh areas, creeks, ponds, swamps, trees, and rain forests. Their habitats must provide enough moisture to keep their skin from drying up, so frogs can only be found in wet areas.

Food:
Frogs are carnivorous predators. They mostly eat insects such as; flies, mosquitoes, moths, and dragonflies. The larger the frog, they larger the size of prey they can hunt. Bigger frogs can consumer grasshoppers and earthworms.

Respiration:
Although frogs breathe air like other land animals, they can also breathe underwater. They do this by absorbing the oxygen present in water through their skin. On land frogs breathe air, but unlike other land animals, they do this with their mouths closed. throat movements help the frog suck in air through their nostrils then into their lungs.

Fun Fact:
As an amphibian, a frog lives both on land and in water. They lay their eggs in water, and hatch as tadpoles. Eventually the tadpole will metamorphoses into an adult frog. It is only then that the frog can live on land.
