Necturus maculosus specimens live in streams, lakes, and ponds in the eastern part of North America. [4] They appear in the southern section of Canada, as far south as Georgia, and from the Midwest United States to North Carolina. Behaviorally, they hide under cover such as rocks and logs during the day and become more active at night. [7]
The origins and evolutionary relationships between the three main groups of amphibians is a matter of debate. A 2005 molecular phylogeny, based on rDNA analysis, suggests that salamanders and caecilians are more closely related to each other than they are to frogs.
Pond life is an umbrella term for all life forms found in ponds. Although there is considerable overlap with the species lists for small lakes and even slow-flowing rivers, pond life includes some species not found elsewhere, and as a biome it represents a unique assemblage of species.

All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
This is a list of amphibians found in the United States. A total of 306 amphibian species have been recorded in the United States , [ 1 ] 2 of which are now extinct. [ 2 ] This list is derived from the database listing of Amphibian Species of the World .
In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia , with three living orders : Anura ( frogs and toads ), Urodela ( salamanders ...
These three areas can have very different abiotic conditions and, hence, host species that are specifically adapted to live there. [1] Two important subclasses of lakes are ponds, which typically are small lakes that intergrade with wetlands, and water reservoirs. Over long periods of time, lakes, or bays within them, may gradually become ...
