As a result, the AArk and its partners created a resource called the Amphibian Conservation Needs Assessment, which is used to prioritize conservation efforts for different species and determine what methods are appropriate for conserving the species.

Instead, they consistute an evolutionary grade (a paraphyletic group ), ancestral to living tetrapods such as lissamphibians (modern amphibians) and amniotes ...
