The Kinosternidae are a family of mostly small turtles that includes the mud turtles and musk turtles. The family contains 25 species within four genera, but taxonomic reclassification is an ongoing process, so many sources vary on the exact numbers of species and subspecies. They inhabit slow-moving bodies of water, often with soft, muddy bottoms and abundant vegetation.
The Blanding's turtle is a semi-aquatic turtle of the family Emydidae. This species is native to central and eastern parts of Canada and the United States. It is considered to be an endangered species throughout much of its range. The Blanding's turtle is of interest in longevity research, as it shows few or no common signs of aging and is physically active and capable of reproduction into eight or nine decades of life.
The alligator snapping turtle is a large species of turtle in the family Chelydridae. The species is native to freshwater habitats in the United States. M. temminckii is one of the heaviest freshwater turtles in the world. It is the largest freshwater species of turtle in North America. It is often associated with, but not closely related to, the common snapping turtle, which is in the genus Chelydra. The specific epithet temminckii is in honor of Dutch zoologist Coenraad Jacob Temminck.
Sternotherus is a genus of turtles in the family Kinosternidae including six species commonly known as musk turtles. The genus is endemic to North America, occurring in the eastern third of the US and southeast Ontario, Canada. Musk glands positioned near the bridge of the shell can produce foul smelling secretions when the turtles are threatened, although gentle handling does not normally provoke a response. Sternotherus are moderately small turtles, with the largest species in the genus, the razor-backed musk turtle, attaining a maximum of 17.6 cm. in shell length. The carapace is characteristically oval and domed, with most species having one or three keels on the back which may become smoother and obscure with age in some species. Musk turtles are generally drab in color, mostly black, gray, brown, olive, or ocher, which aid in camouflaging them in their natural habitats. The head is relatively large and stout, marked with spots, streaks, or strips. The plastron has only 10 or 11 scutes, as opposed to 12, a more common condition in North American turtles. The tail is short, with males having a horny claw like tip.
Staurotypus is a genus of aquatic turtles, commonly known as giant musk turtles, Mexican musk turtles, or three-keeled musk turtles, in the family Kinosternidae. The genus contains two recognized species, which are endemic to Mexico and Central America. Both species are sold and bred as pets.
Sternotherus odoratus is a species of small turtle in the family Kinosternidae. The species is native to southeastern Canada and much of the Eastern United States. It is also known commonly as the common musk turtle, eastern musk turtle, or stinkpot turtle due to its ability to release a foul musky odor from scent glands on the edge of its shell, possibly to deter predation. This turtle is grouped in the same family as mud turtles.
The narrow-bridged musk turtle is a species of turtle in the family Kinosternidae. The species is found in Central America and Mexico.
The Florida softshell turtle is a species of turtle in the family Trionychidae. The species is native to the Southeastern United States.

Cagle's map turtle is a species of turtle in the family Emydidae. The species is endemic to Texas, where it is native to the Guadalupe, San Antonio, and San Marcos Rivers.
The black-knobbed map turtle, formerly known as the black-knobbed sawback, is a small to medium-sized aquatic turtle with light gray skin. Some of the most distinguishing characteristics of the black-knobbed map turtle, and the Graptemys genus, are the protruding "spikes" on the turtle's carapace. This species inhabits mainly the fall lines of rivers in the Mobile Bay drainage, in Alabama and Mississippi.
The flattened musk turtle is a critically endangered species of freshwater turtle in the family Kinosternidae. The species is endemic to the southern United States.
