Amphibians fun quiz

Most amphibians undergo a significant physical transformation, known as metamorphosis, as they transition from their aquatic larval stage to their terrestrial or semi-aquatic adult stage.

Frogs begin as eggs, hatch into aquatic tadpoles, develop into froglets with limbs, and finally mature into adult frogs. Option B describes insect metamorphosis, which includes a pupal stage.

Amphibians are ectotherms, meaning they rely on external environmental sources to regulate their body temperature. They do not generate significant internal body heat like endotherms.

Turtles are reptiles, not amphibians. Frogs, toads, and salamanders all belong to the class Amphibia.

Amphibian skin is thin and permeable, allowing for cutaneous respiration and the absorption of water directly from their environment.
