Two more species, the boreal chorus frog and lesser siren, are considered to be of special concern, although they are not protected under the act. [3] There are no amphibians native to Michigan that are included in the federal Endangered Species Act. [4] Of the over 3400 species of frog and toad worldwide, the majority live in the tropics.
When feasible, this species utilizes caves for thermal refugia during the coldest months of the year. [8] The pickerel frog is a trogloxene species, meaning they occur in caves, but are unable to complete their life cycles there. Though they are most abundant in caves during the winter, they are active deep within caves at almost any time of year.
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs.

Cope's gray treefrog [2] (Dryophytes chrysoscelis) is a species of treefrog found in the United States and Canada. It is almost indistinguishable from the gray treefrog (Dryophytes versicolor), and shares much of its geographic range.
Frogs and toads are broadly classified into three suborders: Archaeobatrachia, which includes four families of primitive frogs; Mesobatrachia, which includes five families of more evolutionary intermediate frogs; and Neobatrachia, by far the largest group, which contains the remaining families of modern frogs, including most common species ...
