A big difference in their development is that amphibians have an aquatic larval form after hatching.

What are two similarities of reptiles and amphibians?

For example, they are both ectothermic, or cold-blooded animals, meaning their body temperature relies on the temperature of their habitat. Reptiles and amphibians also are both vertebrate animals, meaning they have backbones. Reptiles and amphibians also both have excellent eyesight that helps them hunt prey.

How does an amphibian regulate its own body temperature?

Although amphibians exhibit both terrestrial and aquatic characteristic, they are strictly cold-blooded or ectothermic. They do not have the internal mechanisms to regulate their own body temperatures like mammals do. They rely on the external environment to regulate their body temperature.
