"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]
It is a relatively small, toad-like amphibian found in damp, shady habitats. The species is highly fossorial , and feeds primarily on ants. These North American microhylids (Family: Microhylidae ) are distinguished from true toads (genus Bufo ), and other anurans by their moist, smooth skin, their lack of eardrums or tympana , their ...
Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia . They inhabit a wide variety of habitats , with most species living within terrestrial , fossorial , arboreal or freshwater aquatic ecosystems .
In the 10th edition of Systema Naturae, Carl Linnaeus described the Amphibia as: [1]. Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver ...
N. maculosus are good indicators of ecosystem health. This species has frequently been harmed via bycatch events (primarily passive ice fishing), chemical pollutants, and siltation. [ 16 ] Amphibian chytrid fungus (Bd) has been known to affect captive N. maculosus , but it is currently unknown whether it has affected wild N. maculosus .
