Darrel Richmond Frost (born 1951) [1] is an American herpetologist and systematist. He was previously head curator of herpetology at the American Museum of Natural History, as well as president of both the Society for the Study of Amphibians and Reptiles (1998) and the American Society of Ichthyologists and Herpetologists (2006). [1] [2] Four taxa are named in his honor: the toad genus Frostius (which includes Frost's Toad), the tree frog Dendropsophus frosti , [1] Darrel's Chorus Frog Microhyla darreli , [3] and Frost's arboreal alligator lizard Abronia frosti . [4] [5]
Frost became interested in animals after witnessing his father kill a rattlesnake at the age of four. [6] [7] He earned a B.S. in biology from the University of Arizona in 1973, an M.S. in zoology from Louisiana State University in 1978, and a Ph.D. in ecology and systematics from the University of Kansas in 1988. [2] He became an adjunct professor at Columbia University in 2000. [2]
In 1990, Frost was appointed assistant curator of herpetology at the American Museum of Natural History, and in 1995 he was promoted to associate curator. [8] He would later become curator-in-charge [7] and associate dean of science for collections.
Frost and a team of collaborators began work on a catalog of amphibian species, Amphibian Species of the World, in 1980. [9] Frost later explained, "When I started in 1980 on the amphibian catalog, it had been a hundred years since this had been done. So it was an enormous amount of work to catch up because the number of amphibians had basically quadrupled." [10] In 1985, the first edition was published in print. [9] Starting in 1990, Frost completely overhauled the catalog and now publishes it on the website of the American Museum of Natural History. [9] The 1985 catalog had 4,014 species. By 2014, it had grown to more than 7,200, and was being updated almost daily. [7]
Amphibian Species of the World has been described as "the most significant single work in the history of amphibian biology." [11] Frost was awarded the 2013 Sabin Award for Amphibian Conservation in recognition of his work on the catalog. [11] As of 2014, the website is visited more than a million times each year. [7] In 2021 he was awarded the Henry S. Fitch Excellence in Herpetology Award by the American Society of Ichthyologists and Herpetologists. [12]
Frost was lead author of a 2006 study that recommended major taxonomic changes to the amphibian tree of life based on a phylogenetic analysis of 522 species, [13] [14] making it the largest phylogenetic analysis of a vertebrate group to date. [15] Frost has worked in Guatemala, Ethiopia, Mexico, Peru, Namibia, South Africa and Vietnam, [7] and described a number of new species. [16]
The Arthroleptidae are a family of frogs found in sub-Saharan Africa. This group includes African treefrogs in the genus Leptopelis along with the terrestrial breeding squeakers Arthroleptis, and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog (Trichobatrachus).
The Baw Baw frog is a critically endangered species of Australian frog as categorised on the IUCN Red List and listed under the Flora and Fauna Guarantee Act (1988), endemic to Baw Baw National Park. It has suffered a decline in population, mostly due to infection caused by chytrid fungus. Zoos Victoria has undertaken a breeding program to ensure survival of the species which commenced in 2010, and in October 2018 successfully collected the first eggs laid in captivity.
The Mexican burrowing tree frog (Smilisca), also known as the cross-banded tree frog, is a genus of frogs in the family Hylidae found in Mexico, southern Texas and Arizona, Central America, and northwestern South America. In a recent revision of the Hylidae, the two species of the previous genus Pternohyla were included in this genus. Its name is from the Ancient Greek smiliskos, referring to the pointed frontoparietal processes.
Trachycephalus is a genus of frogs, commonly known as the casque-headed tree frogs, in the family Hylidae. They are found in Mexico, Central America, and South America. In a recent revision, the seven species of the genus Phrynohyas were included in this genus, and Phrynohyas is now considered a synonym of Trachycephalus. These frogs inhabit the canopies of tropical rainforests, where they breed in tree cavities, and seldom, if ever, descend to the ground.
Microhyla, commonly known as the rice frogs or narrow-mouthed frogs, is a genus of frogs in the family Microhylidae. It consists of 42 species of diminutive frogs. Members of this genus are widespread from Ryukyu Is. in Japan, and throughout South-east Asia,.
Amphibian Species of the World 6.1: An Online Reference (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range.
Cruziohyla is a genus of frogs in the subfamily Phyllomedusinae. They occur from Nicaragua and Honduras in Central America south to the Amazon Basin in South America. This genus was erected in 2005 following a major revision of the Hylidae and fully reviewed in 2018. Species in this genus were previously placed in the genera Agalychnis or Phyllomedusa.
Helen Beulah Thompson Gaige was an American herpetologist, curator of Reptiles and Amphibians for the Museum of Zoology at the University of Michigan, and a specialist in neotropical frogs.
Norman Edouard "Kibe" Hartweg was an American herpetologist, Curator of Herpetology for the Museum of Zoology at the University of Michigan, and president of the American Society of Ichthyologists and Herpetologists. He was a specialist in the taxonomy and distribution of turtles, and is honored by having a subspecies of turtle named after him: the western spiny softshell turtle, Apalone spinifera hartwegi. He is also credited with having described several new species, including the Big Bend slider, Trachemys gaigeae, the Oaxacan patchnose snake, Salvadora intermedia, and Dunn's hognose pit viper, Porthidium dunni.
Charles Mitchill Bogert was an American herpetologist, and curator of herpetology and researcher for the American Museum of Natural History.

Cryptobatrachus boulengeri, also known as Boulenger's backpack frog, is a species of frogs in the family Hemiphractidae. It is endemic to Sierra Nevada de Santa Marta in northern Colombia. The specific name honours George Albert Boulenger, an eminent herpetologist.
Lynchius parkeri, also known as Parker's Andes frog, is a species of frog in the family Strabomantidae. It is found in northern Peru and southern Ecuador. The specific name parkeri honors Hampton Wildman Parker, English zoologist and herpetologist.
Doris Mable Cochran was an American herpetologist and custodian of the American Natural Collection at the Smithsonian Institution in Washington, D.C., for many years.
Abronia smithi is a species of lizard in the family Anguidae. Known by the common name Smith's arboreal alligator lizard, the species is endemic to the state of Chiapas in Mexico.
Richard George Zweifel was an American herpetologist, who classified several species in the American Southwest and in Australia, including the rattling frog. Zweifel contributed immensely to the documentation of the nowadays Aspidoscelis costatus species. Out of the eight costata subspecies, Dr. Zweifel reported and named five of them. Zweifel worked at the American Museum of Natural History from 1954 to 1989, and was Herpetology Department Chairman from 1968 to 1980.
Benjamin Shreve (1908–1985) was an American amateur herpetologist. He was from a wealthy Boston family of jewellers and worked at the Harvard Museum of Comparative Zoology as a volunteer. He was trained by Arthur Loveridge to deal with materials from elsewhere than Africa. Shreve described many species from the West Indies together with Thomas Barbour. In these papers, Shreve is said to have done the "spadework" while Barbour wrote "florid" introductions.
Polypedates iskandari is a species of frogs in the family Rhacophoridae. It is endemic to Sulawesi, Indonesia. It belongs to the Polypedates leucomystax species complex; it was split from Polypedates leucomystax in 2011 based on a morphometric analysis. This split has been challenged because male vocalizations between specimens from Sulawesi and Java show only minor differences and because genetic differences are low.
Rohanixalus is a genus of tree frogs in the family Rhacophoridae native to the Andaman islands and Indo-Burma region. The genus was established in 2020 by Indian herpetologist S.D. Biju of the University of Delhi and his colleagues. The genus comprises eight species.
Dendropsophus frosti, the acre tree frog, is a frog in the family Hylidae. It is endemic to in South America. Scientists have seen it at two sites, one in Colombia and one in Peru.
