Amphibians Site

Amphibians are a unique class of cold-blooded vertebrates, such as frogs, toads, and salamanders, known for their "double life"—spending part of their life cycle in water and part on land. They typically hatch from jelly-like eggs as aquatic larvae with gills, then undergo metamorphosis to develop lungs and legs as terrestrial adults. Beyond these common traits, amphibians are highly sensitive to environmental changes due to their semi-permeable skin, which they use for breathing and moisture absorption. Key Identification & Biology : : Tailless species including and toads .

: Many species use vomerine teeth on their upper jaw to hold prey rather than chew it. Their skin often contains granular glands that can secrete toxins as a defense mechanism. amphibians

: Legless, burrowing creatures called caecilians. Amphibians are a unique class of cold-blooded vertebrates,

: Tailed species like salamanders , newts , and sirens. Key Identification & Biology : : Tailless species

: While most adults use lungs, they heavily rely on cutaneous respiration , absorbing oxygen directly through their moist skin. Field Guides & Resources
