Crocodiles or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodylinae, all of whose members are considered true crocodiles, is classified as a biological subfamily. A broader sense of the term crocodile, Crocodylidae, is not used in this article. The term crocodile here applies to only the species within the subfamily of Crocodylinae. The term is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans, the gharial and false gharial, and all other living and fossil Crocodylomorpha.

The American crocodile is a species of crocodilian found in the Neotropics. It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida and the coasts of Mexico to as far south as Peru and Venezuela.

Because of this, it is the most commonly traded species of turtle in the world.

Scincella is a genus of lizards in the skink family, Scincidae, commonly referred to as ground skinks. The exact number of species in the genus is unclear, as taxonomic reclassification is ongoing, and sources vary widely. Scincella species primarily range throughout the temperate regions of the world and are typically small, fossorial lizards, which consume a wide variety of arthropods.

No subspecies are currently recognized.
