Before revision: During their life cycle, all anamniote classes pass through a completely aquatic egg stage, as well as an aquatic larval stage during which all hatchlings morphologically resemble tiny finless fish (known as a fry or a tadpole for fish and amphibians, respectively), before reaching adult forms (which might be aquatic or semiaquatic), thus indicating their close physiological relationship.
