Subcategories of Amphibians
The subcategories of amphibians include frogs, toads, salamanders, newts, and caecilians. These creatures are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Amphibians typically have moist skin, lay eggs in water, and undergo metamorphosis from a larval stage to an adult form. They play important roles in ecosystems as both predators and prey, contributing to the balance of aquatic and terrestrial food chains.
