The common mudpuppy (Necturus maculosus) is a species of salamander in the family Proteidae. [3] It lives an entirely aquatic lifestyle in parts of North America in lakes, rivers, and ponds. It goes through paedomorphosis and retains its external gills. [4]
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.
Frogs in a pond. 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.

Modern caecilians are a clade, the order Gymnophiona / ˌ dʒ ɪ m n ə ˈ f aɪ ə n ə / (or Apoda / ˈ æ p ə d ə /), one of the three living amphibian groups alongside Anura and Urodela (salamanders). Gymnophiona is a crown group, encompassing all modern caecilians and all descendants of their last common ancestor.

In the life cycle of a frog, a female lays her eggs in a shallow pond or creek, where they will be sheltered from the current and from predators. The eggs, known as frogspawn hatch into tadpoles . The tadpoles develop gradually into adolescent froglets and finally the froglet develops into an adult frog.
