What type of animal is a frog?

Frogs are classified as amphibians, which is the correct answer. Amphibians are characterized by their ability to live both in water and on land. Frogs, in particular, begin their lives as aquatic larvae (tadpoles) that breathe through gills. As they mature, they undergo metamorphosis, developing lungs to breathe air as adults, which allows them to inhabit terrestrial environments.

Frogs also possess smooth, moist skin that facilitates respiration and absorption of water, a distinguishing feature of amphibians. This classification is crucial as it differentiates them from mammals, which have fur or hair and give live birth; reptiles, which are primarily terrestrial, have scaly skin and lay eggs; and fish, which are aquatic animals that use gills to breathe underwater. Understanding these classifications can help in recognizing the unique biological characteristics and life cycles of frogs.
