Leopard frog

Leopard frog is a generic name used to refer to various species in the true frog genus Lithobates. They all have similar coloration: brown or green with spots that form a leopard pattern. They are distinguished by their distribution and behavioral, morphological, and genetic differences. The range of the various species of leopard frogs extends from the Hudson Bay in Canada, throughout the United States, throughout Mexico and other parts of Central America, and possibly the very northern section of South America.

Leopard frogs are grouped in the genus Lithobates, along with many other different frogs such as the American bullfrog.

New species
Several leopard frog species look very similar to each other, and even within a population there is a lot of variation. Some populations may actually be cryptic species complexes.

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 New York, and Staten Island; the new species was first distinguished by its short, repetitive croak, distinct from the "long snore" or "rapid chuckle" of other leopard frog species in that area (L. pipiens and L. sphenocephalus). This distinct species has been identified as far south as southeastern Virginia and northeastern North Carolina. On 30 October 2014, it was announced that the frog found in March 2012 has been described as a new species: the Atlantic Coast leopard frog (Lithobates kauffeldi) that once inhabited Manhattan, New York.
