Amphibians are a diverse group of animals that includes frogs, toads, salamanders, newts, and caecilians. Here are some common amphibians and their characteristics:
Frogs and toads: These are the most familiar amphibians. They have smooth, moist skin, long hind legs, and webbed feet that allow them to jump and swim. Frogs are generally found near water, while toads can be found in a wider range of habitats.
Salamanders: Salamanders are typically slender-bodied with long tails and short legs. They have smooth, moist skin and are often found in or near water. Some species can regenerate lost body parts, including limbs.
Newts: Newts are similar to salamanders, but they are aquatic during their juvenile stage and develop lungs as adults, allowing them to breathe air. They have bright, distinctive coloring to warn predators of their poisonous skin.
Caecilians: Caecilians are legless, worm-like amphibians that live underground or in freshwater habitats. They have highly reduced eyes and rely on a keen sense of smell to navigate their environment.
Overall, amphibians are cold-blooded, meaning their body temperature varies with the temperature of their environment. They also have a unique lifecycle that includes an aquatic larval stage and a terrestrial adult stage.
