What are amphibians and their adaptations?
Some amphibians have developed the ability to only exist in watery environments. Many aquatic species have gills that enable them to breathe in water, and many aquatic species spend the majority or all of their lives in the water.
Amphibians include salamanders, toads, frogs, and toads. Amphibians have life cycles that involve both land and water time. They lack scales because their skin must keep moist to absorb oxygen.. Reptiles have only lungs, not gills like amphibians do, and their scaly, dry skin prevents them from The collective term for reptiles and amphibians is herpetofauna, or "herps." All herps lack an internal thermostat because they are "cold-blooded." Instead, individuals are forced to control body temperature through their interactions with the outside world. For instance, a lizard may regulate its body temperature via "shuttling" actions, such as going in and out of shelter, and a turtle can warm itself by basking in the sun, and a tail resembling a paddle are three well-known examples of aquatic adaptations.
