Sirenidae, the sirens, are a family of neotenic aquatic salamanders. Family members have very small fore limbs and lack hind limbs altogether. In one species, the skeleton in their fore limbs is made of only cartilage. In contrast to most other salamanders, they have external gills bunched together on the neck in both larval and adult states. Sirens are found only in the Southeastern United States and northern Mexico.
The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern United States covering 54,400 square miles (141,000 km2) of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak. Historically the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries. The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States. The United States Environmental Protection Agency (EPA) defines most of this ecoregion as the South Central Plains.
The Cuban tree frog is a large species of tree frog that is native to Cuba, the Bahamas, and the Cayman Islands; but has become invasive in several other places around the Americas. Its wide diet and ability to thrive in urban areas has made it a highly invasive species with established colonies in places such as Florida, the Hawaiian island of Oahu, and the Caribbean Islands. These tree frogs can vary in size from 2 to 5.5 inches in length. Due to their large size, Cuban tree frogs can eat a wide variety of things, particularly native tree frogs, and their removal has shown to result in an increase in the amount of native tree frogs in an area. The tadpoles of Cuban tree frogs also heavily compete with native frog tadpoles, which can cause negative effects in body mass, size at metamorphosis, and growth rates for the native tadpoles.
The two-toed amphiuma is an aquatic salamander widely distributed in the southeastern United States. It is commonly, but incorrectly, called "congo snake", "conger eel" or the "blind eel".

Dryophytes gratiosus, commonly known as the barking tree frog, is a species of tree frog endemic to the south-eastern United States.
The southern dwarf siren, is a perennibranch salamander lacking hind legs. Found exclusively in Florida, it is one of two currently recognized species of dwarf sirens. Two subspecies are currently recognized; P. a. axanthus, the narrow-striped dwarf siren, and P. a. belli, the Everglades dwarf siren.
The Sierran chorus frog or Sierran treefrog is native to the state of California, Idaho, Oregon, Nevada, and Montana. It has a range from the West Coast of the United States from Central California inland through Idaho. They can live at sea level, but also up to more than 10,000 feet utilizing trees, ponds, grasslands, farmlands, meadows, and lakes as habitats. These frogs, alike other, reproduce in aquatic settings. They occur in shades of greens or browns and can change colors over periods of hours and weeks. These colors help them easily blend into the background and hard for the eye to catch.
