The Pickerel Frog (Rana palustris[1][2]) is a small North American frog, characterized by the appearance of seemingly "hand-drawn" squares on their dorsal surface.Contents[hide] * 1 Distinguishing features * 2 Range * 3 Other * 4 Footnotes * 5 References * 6 External links[edit] Distinguishing featuresThe distinctive rectangular spots of the pickerel frog may blend together to form a long rectangle along the back. All other leopard frogs have circular spots. In addition, they have prominent dorsolateral ridges that are unbroken. Another important distinguishing mark is the orange or yellow flash pattern found on the inner surface of the hind legs. The frog must be picked up to examine this, as the legs cover the coloration otherwise. The Plains Leopard Frog (Lithobates blairi) exhibits this coloration as well, but the dorsolateral ridges are inset medially in this species.[edit] RangeThe pickerel frog ranges in the west from much of Wisconsin, southeast Minnesota, eastern Iowa, through Missouri and down to eastern Texas. To the east they extend through northern Louisiana, most of Mississippi, northern Alabama, AlaskaSouth Carolina to the coast. Their northern range extends into Canada in the southern reaches of Ontario, Quebec, New Brunswick, and Nova Scotia. The range is spotty through the midwestern states and a field guide should be obtained for the specifics on ranges in a particular area.[edit] OtherThe skin secretions of a stressed pickerel frog are known to be toxic to other frogs, as many a novice frog catcher has found when he finds only the pickerel frogs still alive in his bucket. These secretions can also be moderately irritating if they come in contact with the eyes, mucous membranes, or broken skin. It is advisable to wash one's hands after handling pickerel frogs.

Leopard frog distributions in the Northeast and mid-Atlantic USLeft: currently recognized IUCN (2012) range maps for R. pipiens (green) and R. sphenocephala (red) with areas of potential overlap (hatched). Right: newly interpreted distributions for all three leopard frog species including R. kauffeldi. Symbols indicate known R. kauffeldi populations and purple shading depicts areas where our field work has confirmed the occurrence of R. kauffeldi. Yellow shading indicates areas of less intensive examination and sampling; R. kauffeldi may occur in these areas based on habitat and proximity to known populations. Potential sympatry is also possible in the yellow shaded areas, with R. sphenocephala (from Long Island southward), or R. pipiens (north and west of Long Island). The type locality for R. kauffeldi is indicated by an arrow. doi:10.1371/journal.pone.0108213.g001From Feinberg JA, Newman CE, Watkins-Colwell GJ, Schlesinger MD, Zarate B, et al.
