|Southern Leopard Frog (Rana sphenocephala)|
A leopard frog (sometimes called a meadow frog) can mean any frog of about 14 species within the true frog genus. They are generally similarly colored--green with prominent black spotting that sometimes appears as a leopard pattern. They are distinguished by their distribution and certain rather subtle ecological, behavioral, morphological and genetic traits. Their range in the North-American subcontinent extends throughout temperate and subtropical North America to northern Mexico, with some species found even further south. They are also found in Europe.

In March 2012, it was announced that DNA testing had confirmed that a new species of leopard frog had been found whose habitat was centered near New York's Yankee Stadium and included northern New Jersey, southeastern mainland New York, and Staten Island; the new still unnamed species is part of a cryptic species complex that was first distinguished by its short, repetitive croak, distinct from the "long snore" or "rapid chuckle" of other area leopard frog species.
