"Herp" is a vernacular term for non-avian reptiles and amphibians. It is derived from the archaic term "herpetile", with roots back to Linnaeus's classification of animals, in which he grouped reptiles and amphibians in the same class. There are over 6700 species of amphibians [9] and over 9000 species of reptiles. [10]
Common Garter Snake. Herping is the act of searching for amphibians or reptiles. [1] [2] The term, often used by professional and amateur herpetologists, comes from the word "herp", which comes from the same Greek root as herpetology, herpet-, meaning "creeping".
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders , historically combined with that of modern amphibians , is called herpetology .
Reptiles, from Nouveau Larousse Illustré, 1897–1904, notice the inclusion of amphibians (below the crocodiles). In the 13th century, the category of reptile was recognized in Europe as consisting of a miscellany of egg-laying creatures, including "snakes, various fantastic monsters, lizards, assorted amphibians, and worms", as recorded by Beauvais in his Mirror of Nature.

The earliest known true snake fossils (members of the crown group Serpentes) come from the marine simoliophiids, the oldest of which is the Late Cretaceous (Cenomanian age) Haasiophis terrasanctus from the West Bank, [1] dated to between 112 and 94 million years old. [25] Based on genomic analysis it is certain that snakes descend from lizards ...
This is a checklist of American reptiles found in Northern America, based primarily on publications by the Society for the Study of Amphibians and Reptiles (SSAR). [1] [2] [3] It includes all species of Bermuda, Canada, Greenland, Saint Pierre and Miquelon, and the United States including recently introduced species such as chameleons, the Nile monitor, and the Burmese python.
However, the research goes on to note that "to date, only a handful of snakes have been observed to hunt in groups, and coordination among them — or among any other group-hunting reptiles ...
Living non-avian reptiles form a paraphyletic group that consists of over 9,000 species of crocodiles, turtles, and lepidosaurs. The most diverse group, Lepidosauria , is first known from the Middle Triassic (240 million years ago) fossils, but likely originated in the Permian (approximately 300-250 million years ago). [ 1 ]
