What is the term for the class of vertebrates that undergo metamorphosis from aquatic to terrestrial life?

• A. Amphibians
• B. Reptiles
• C. Fish
• D. Mammals

Answer: (A)

The term for the class of vertebrates that undergo metamorphosis from aquatic to terrestrial life is amphibians. This group includes well-known species such as frogs, toads, and salamanders. Amphibians typically start their life cycle as aquatic larvae (tadpoles) that possess gills for breathing underwater. As they mature, they undergo significant physiological transformations—including the development of lungs and limbs—that allow them to transition to a terrestrial environment, thus enabling them to live both in water and on land. This dual lifestyle is a defining characteristic of the class, highlighting the remarkable adaptability of these organisms to different habitats over their life cycles.
