Turtles (Testudines)

Mexico has a total of 54 species of turtle, grouped into 7 families and 20 genera. Among them, there are 6 marine species, almost all of them in danger of extinction.

Cheloniidae

Order: Testudines ·
Family: Cheloniidae
Sea turtles are a family of large turtles found in all tropical seas and some subtropical and temperate seas. Sea turtles developed from land turtles about 120 million years ago and are well adapted to life in the sea. They feed mainly on jellyfish, crustaceans and squid. There are 5 or 6 species in the world, of which at least 5 are currently in danger of extinction.

Dermochelyidae

Order: Testudines ·
Family: Dermochelyidae
The leatherback sea turtle is the largest of all existing turtles and can reach a length of 2 meters and a weight of more than 600 kg. It is found in all tropical or subtropical seas. Unlike most sea turtles, leatherbacks are often found in the colder waters of temperate zones. It is the only extant species of the Dermochelyidae family and is considered critically endangered. All other species in this family are only known as fossils.Dermochelys coriacea CR

Chelydridae

Order: Testudines ·
Family: Chelydridae
Chelydrids are a family of freshwater turtles that is made up of seven extinct genera and two extant genera, both native to the American continent. The existing genera are the snapping turtles with three species, and the alligator turtles with a single species. Of the total of four existing species, 2 occur in Mexico.

Dermatemydidae

Order: Testudines ·
Family: Dermatemydidae
The white turtle is the only existing species in the Dermatemydidae family. It is a nocturnal, aquatic turtle that lives in large rivers and lakes in Central America, from southern Mexico to northern Honduras. It is one of the most exploited turtles in the world and is classified as a critically endangered species by the IUCN. It is quite large and can weigh around 20 kg. Its flattened shell can reach a length of 65 cm and is generally gray or almost black in color. Its plastron is normally cream colored.Dermatemys mawii Gray, 1847 CR

Crocodilians (Crocodylia)

Crocodylidae

Order: Crocodylia ·
Family: Crocodylidae
Crocodiles are a family of archosaur sauropsids. This family includes 14 species of large semi-aquatic reptiles that inhabit tropical areas of the world. Crocodiles tend to congregate in freshwater habitats, such as rivers, lakes, wetlands, and sometimes brackish water. They are ambush hunters who usually wait for their prey, generally fish or land animals, to approach, before attacking them. They feed mainly on vertebrates such as fish, reptiles and mammals, and sometimes invertebrates such as mollusks and crustaceans, depending on the species. As cold-blooded predators, they have a slow metabolism and can therefore survive long periods without food. Despite their slow appearance, crocodiles are very fast over short distances, even out of water.Crocodylus acutus Cuvier, 1807 VUCrocodylus moreletii Duméril & Bocourt, 1851

Alligatoridae

Order: Crocodylia ·
Family: Alligatoridae
The alligatorids are a family of crocodilian sauropsids native to the Americas. It includes the extant genera Alligator, Caiman, Melanosuchus and Paleosuchus, as well as numerous extinct genera. Of the 7 species that inhabit America, 2 occur in Mexico.Alligator mississippiensis Caiman crocodilus Linnaeus, 1758

Anguidae

Order: Squamata ·
Family: Anguidae
Anguids are a family of anguimorphic scaly sauropsids that includes glass lizards, snapdragons, northern alligator lizards, and alicante lizards. Species of the Anguinae subfamily are characterized by leg atrophy, despite the fact that they are not directly related to snakes or amphisbaenae, as this is a notable case of evolutionary convergence. The family was described by the English naturalist John Edward Gray in 1825. The distribution of Anguidae spans the Old and New Worlds. It is only absent in Australia. Most species are terrestrial, living in the leaf litter on the forest floor. The anguid family is divided into four subfamilies, 10 non-extinct genera, and contains 94 species. In Mexico there are 50 species.Abronia antauges Cope, 1866Abronia aurita Cope, 1869 ENAbronia bogerti Tihen, 1954 DDAbronia chiszari Smith & Smith, 1981 ENAbronia cuetzpali Campbell, Solano-Zavaleta, Flores-Villela, Caviedes-Solis & Frost, 2016 NEAbronia deppii Wiegmann, 1828 ENAbronia fuscolabialis Tihen, 1944 ENAbronia gadovii Boulenger, 1913Abronia graminea Cope, 1864 VUAbronia juarezi Karges & Wright, 1987Abronia leurolepis Campbell & Frost, 1993 DDAbronia lythrochila Smith & Álvarez del Toro, 1963 LCAbronia martindelcampoi Flores-Villela & Sánchez-H., 2003 ENAbronia matudai Hartweg & Tihen, 1946 ENAbronia mitchelli Campbell, 1982 DDAbronia mixteca Bogert & Porter, 1967Abronia moreletii Bocourt, 1872 LCAbronia morenica Clause, Luna-Reyes & Nieto-Montes De Oca, 2020 NEAbronia oaxacae Günther, 1885 VUAbronia ochoterenai Martín del Campo, 1939 DDAbronia ornelasi Campbell, 1984 DDAbronia ramirezi Campbell, 1994 DDAbronia reidi Werler & Shannon, 1961 DDAbronia smithi Campbell & Frost, 1993 LCAbronia taeniata Wiegmann, 1828 ENAbronia viridiflava Bocourt, 1873Abronia zongolica García-Vázquez, Clause, Gutiérrez-Rodríguez, Cazares-Hernández & de la Torre-Loranca, 2022 NEBarisia herrerae Zaldîvar-Riverón & Nieto-Montes de Oca, 2002Barisia imbricata Wiegmann, 1828Barisia levicollis Stejneger, 1890Barisia rudicollis Desertum lugoi McCoy, 1970Elgaria kingii Gray, 1838Elgaria multicarinata Elgaria paucicarinata Elgaria velazquezi Grismer & Hollingsworth, 2001Gerrhonotus farri Bryson & Graham, 2010Gerrhonotus infernalis Baird, 1859Gerrhonotus lazcanoi Banda-Leal, Nevárez-de los Reyes, Bryson, 2017Gerrhonotus liocephalus Wiegmann, 1828Gerrhonotus mccoyi García-Vázquez, Contreras-Arquieta, Trujano-Ortega & Nieto-Montes de Oca, 2018Gerrhonotus ophiurus Cope, 1867Gerrhonotus parvus Knight & Scudday, 1985Ophisaurus ceroni Holman, 1965Ophisaurus incomptus McConkey, 1955

Gekkonidae

Order: Squamata ·
Family: Gekkonidae
Geconids or geckos are a family of scaly sauropsids, which includes small to medium-sized species found in temperate and tropical climates around the world. They have several peculiar features that clearly distinguish them from other lizards. They are unique in their vocalization, as they make screeching noises in their interactions with other geckos. They are nocturnal, with large eyes and equipped with vertical lobed pupils that allow an extraordinary margin of variation in their opening. Many species have sticky pads on the soles of their feet that allow them to climb smooth vertical surfaces and even navigate roofs. The gecko family has a global distribution. 6 species occur in Mexico.Gehyra mutilata Hemidactylus brookii Gray, 1845Hemidactylus frenatus Schlegel, 1836Hemidactylus mabouia Hemidactylus turcicus

Its distribution area includes Mexico, Central and South America up to Ecuador. There are nine recognized species of corythophanids, of which 6 occur in Mexico.Basiliscus vittatus Wiegmann, 1828Corytophanes cristatus Corytophanes hernandesii Corytophanes percarinatus Duméril, 1856Laemanctus longipes Wiegmann, 1834Laemanctus serratus Cope, 1864

Iguanidae

Order: Squamata ·
Family: Iguanidae
The iguanids are a family of lizards whose distribution extends from the southern United States, Central America to Paraguay, and from the Caribbean islands to the Galapagos Islands and Fiji. Iguanids can reach lengths that vary between and. The tail is often longer than the rest of the body. They often have a dewlap that helps regulate body temperature, and dorsal spines that are more pronounced in males than in females. Some species are terrestrial, others prefer to live in trees or rocks. Males are usually territorial and defend their territory against other males, but tolerate females. All iguanas are oviparous. The nests are usually quite large, often several females lay their eggs in proximity to other nests to facilitate their defense against predators. Juveniles feed primarily on insects and other invertebrates, while adults, especially in larger species, switch to a primarily plant diet. 16 species of iguanids occur in Mexico.Ctenosaura acanthura Ctenosaura alfredschmidti Köhler, 1995 NTCtenosaura clarki Bailey, 1928Ctenosaura defensor Ctenosaura hemilopha Ctenosaura oaxacana Köhler & Hasbun, 2001Ctenosaura pectinata Ctenosaura quinquecarinata Ctenosaura similis Dipsosaurus dorsalis Iguana iguana Sauromalus ater Duméril, 1856Sauromalus hispidus Stejneger, 1891Sauromalus klauberi Shaw, 1941Sauromalus slevini Van Denburgh, 1922Sauromalus varius Dickerson, 1919

Typhlopidae

Order: Squamata ·
Family: Typhlopidae
Typhlopids are a family of blind snakes that mainly inhabit the tropical regions of Africa, America, Asia, and Australia. They live in burrows, and since they have no use for vision, their eyes are reduced to vestiges, although they can detect light. They have teeth in the upper jaw. The tail ends with a horn-shaped scale. Most of these species are oviparous. 6 genera are recognized, containing 203 species. 3 species occur in Mexico.Amerotyphlops microstomus Amerotyphlops tenuis

Boidae

Order: Squamata ·
Family: Boidae
Boids or boas are a family of non-venomous snakes, native to America, Africa, Europe, Asia and some Pacific islands. They are constrictor snakes, meaning they kill their prey by constriction, enclosing them in their rings, applying and maintaining enough pressure to inhibit inhalation; The prey finally succumbs to suffocation. 43 species are distinguished, grouped into 2 subfamilies and 8 genera. 4 species occur in Mexico.Boa constrictor Linnaeus, 1758Exiliboa placata Bogert, 1968Lichanura trivirgata Cope, 1861Ungaliophis continentalis Müller, 1880

Loxocemidae

Order: Squamata ·
Family: Loxocemidae
The loxocemids are a family of constrictor snakes. This family consists of a single genus and a single species Loxocemus bicolor. It can reach a length of, but usually measures. It has a triangular head, a fairly robust cylindrical body, a little flattened dorsoventrally in the posterior region; short and conical tail. The eyes are small; The scales are wide and smooth, all similar except for a slightly elongated ventral row. They have vestiges of a pelvic girdle and a claw-shaped structure like in boids. They are excavators, but not as specialized. They are only found in specific areas of the rainforests of Mexico and Central America.Loxocemus bicolor Cope, 1861

Colubridae

Order: Squamata ·
Family: Colubridae
The colubrids are a family of snakes with a global distribution, except Antarctica. They are characterized by having their heads covered with large scales of a typical arrangement. The dorsal and lateral scales of the body are approximately rhomboidal in outline; On the ventral side they have a single row of widened scales. They are generally diurnal, with well-developed eyes and mainly circular pupils. The majority is terrestrial, but there are also burrowing, amphibian, aquatic, arboreal and even gliding species. Although most colubrids are nonvenomous, some species, such as those in the genus Boiga, can produce bites with significant medical effects. Colubrids form the largest family of snakes. 134 species of colubrids occur in Mexico.Arizona elegans Kennicott 1859Bogertophis rosaliae Bogertophis subocularis Chilomeniscus savagei Cliff, 1954Chilomeniscus stramineus Cope, 1860Chionactis occipitalis Chionactis palarostris Coluber anthonyi Coluber aurigulus Coluber bilineatus Coluber constrictor Linnaeus, 1758Coluber flagellum Shaw, 1802Coluber fuliginosus Coluber lateralis Coluber mentovarius Coluber schotti Coluber taeniatus Conopsis acuta Conopsis amphisticha Conopsis biserialis Conopsis lineata Conopsis megalodon Conopsis nasus Dendrophidion vinitor Smith, 1941Drymarchon corais Drymarchon melanurus Drymobius chloroticus Drymobius margaritiferus Ficimia hardyi MENDOZA-QUIJANO & Smith, 1993Ficimia olivacea Gray, 1849Ficimia publia Cope, 1866Ficimia ramirezi Smith & Langebartel, 1949Ficimia ruspator Smith & Taylor, 1941Ficimia streckeri Taylor, 1931Ficimia variegata Geagras redimitus Cope, 1876Gyalopion canum Gyalopion quadrangulare Lampropeltis alterna Lampropeltis californiae Lampropeltis knoblochi Lampropeltis mexicana Lampropeltis pyromelana Lampropeltis ruthveni Blanchard, 1920Lampropeltis splendida Lampropeltis triangulum Lampropeltis webbi Bryson, Dixon & Lazcano, 2005Lampropeltis zonata Leptophis ahaetulla Leptophis diplotropis Leptophis mexicanus Duméril, Bibron & Duméril, 1854Leptophis modestus VUMastigodryas cliftoni Mastigodryas dorsalis Mastigodryas melanolomus Opheodrys aestivus Opheodrys vernalis Oxybelis aeneus Oxybelis fulgidus Pantherophis bairdi Pantherophis emoryi Phyllorhynchus browni Stejneger, 1890Phyllorhynchus decurtatus Pituophis catenifer Blainville, 1835Pituophis deppei Pituophis lineaticollis Pituophis melanoleucus Pituophis vertebralis Pliocercus elapoides Cope, 1860Pliocercus wilmarai Smith, Perez-Higareda & Schiszar, 1996Pseudelaphe flavirufa Pseudoficimia frontalis Pseustes poecilonotus Rhinocheilus lecontei Baird & Girard, 1853Salvadora bairdi Jan 1860Salvadora grahamiae Baird & Girard, 1853Salvadora hexalepis Salvadora intermedia Hartweg, 1940Salvadora lemniscata Salvadora mexicana Scaphiodontophis annulatus Senticolis triaspis Sonora aemula Sonora michoacanensis Sonora mutabilis Stickel, 1943Sonora semiannulata Baird & Girard, 1853Spilotes pullatus Stenorrhina degenhardtii Stenorrhina freminvillei Symphimus leucostomus Cope, 1869Symphimus mayae Sympholis lippiens Cope, 1861Tantilla atriceps Tantilla bocourti Tantilla briggsi Savitzky & Smith, 1971Tantilla calamarina Cope, 1866Tantilla cascadae Wilson & Meyer, 1981Tantilla ceboruca Canseco-Márquez, Smith, Ponce-Campos, Flores-Villela & Campbell, 2007Tantilla coronadoi Hartweg, 1944Tantilla cuniculator Smith, 1939Tantilla deppei Tantilla flavilineata Smith & Burger, 1950Tantilla gracilis Baird & Girard, 1853Tantilla hobartsmithi Taylor, 1936Tantilla impensa Campbell, 1998Tantilla jani Tantilla johnsoni Wilson, Vaughn & Dixon, 1999Tantilla melanocephala Tantilla moesta Tantilla nigriceps Kennicott 1860Tantilla oaxacae Wilson & Meyer, 1971Tantilla planiceps Tantilla robusta Canseco-Márquez, MENDELSOHN & GUTIÉRREZ-MAYÉN, 2002Tantilla rubra Cope, 1876Tantilla schistosa Tantilla sertula Wilson & Campbell, 2000Tantilla shawi Taylor, 1949Tantilla slavensi Pérez-Higareda, Smith & Smith, 1985Tantilla striata Dunn, 1928Tantilla taeniata Bocourt, 1883Tantilla tayrae Wilson, 1983Tantilla triseriata Smith & Smith, 1951Tantilla vulcani Campbell, 1998Tantilla wilcoxi Stejneger, 1902Tantilla yaquia Smith, 1942Tantillita brevissima Tantillita canula Tantillita lintoni Trimorphodon biscutatus Trimorphodon lambda Cope, 1886Trimorphodon lyrophanes Trimorphodon paucimaculatus Taylor, 1938Trimorphodon tau Cope, 1870Trimorphodon vilkinsonii Cope, 1886

Elapidae

Order: Squamata ·
Family: Elapidae
Elapids are a family of highly venomous snakes that live in tropical and subtropical regions of the world. They are characterized by having fixed hollow fangs through which they inject venom. They have a size that can vary from to more than in length. Some of its best-known members are cobras, coral snakes, mambas, and sea snakes. Outwardly, terrestrial elapids are similar to colubrids; Almost all of them have a long, thin body, a head covered with large scales and eyes with round pupils. Furthermore, their behavior is generally quite active, and many species are oviparous. Sea snakes, which are also elapids, have adapted to marine life in different ways and to varying degrees. Their characteristics may include laterally flattened bodies and rudder tails for swimming, as well as the ability to excrete salt. Currently, a total of 351 species are distinguished globally. 19 species occur in Mexico, of which 17 are coral snakes.Hydrophis platurus Laticauda colubrina Micruroides euryxanthus Micrurus bernadi Micrurus bogerti Roze, 1967Micrurus browni Schmidt & Smith, 1943Micrurus diastema Micrurus distans Micrurus elegans Micrurus ephippifer Micrurus laticollaris Micrurus latifasciatus Schmidt, 1933Micrurus limbatus Fraser, 1964Micrurus nebularis Roze, 1989Micrurus nigrocinctus Micrurus pachecogili Campbell, 2000Micrurus proximans Smith & Chrapliwy, 1958Micrurus tamaulipensis Lavin-Murcio & Dixon, 2004Micrurus tener Baird & Girard, 1853

Viperidae

Order: Squamata ·
Family: Viperidae
The viperids are a family of highly venomous snakes that comprises four subfamilies. The subfamily Crotalinae, commonly known as "pit vipers", are the only viperids native to America. They have a loreal pit, a hole on each side of the head between the eye and the nostril; It is a thermoreceptor organ that is very sensitive to temperature variations and is used to detect warm-blooded prey. Approximately 321 species of viperids are distinguished, grouped into 32 genera. In Mexico, 10 genera and 59 species occur.Agkistrodon bilineatus Günther, 1863 NTAgkistrodon contortrix Agkistrodon russeolus Gloyd, 1972Agkistrodon taylori Burger & Robertson, 1951Atropoides mexicanus Atropoides nummifer Atropoides occiduus Atropoides olmec Bothriechis aurifer VUBothriechis bicolor Bothriechis rowleyi Bothriechis schlegelii Bothrops asper Cerrophidion godmani Cerrophidion petlalcalensis Lopéz-Luna, Vogt & Torre-Loranca, 1999Cerrophidion tzotzilorum Crotalus aquilus Klauber, 1952Crotalus atrox Baird & Girard, 1853Crotalus basiliscus Crotalus catalinensis Cliff, 1954 CRCrotalus cerastes Hallowell, 1854Crotalus cerberus Crotalus culminatus Klauber, 1952Crotalus durissus Linnaeus, 1758Crotalus enyo Crotalus ericsmithi Campbell & Flores-Villela, 2008Crotalus intermedius Troschel, 1865Crotalus lannomi Tanner, 1966Crotalus lepidus Crotalus mitchellii Crotalus molossus Baird & Girard, 1853Crotalus oreganus Holbrook, 1840Crotalus ornatus Hallowell, 1854Crotalus polystictus Crotalus pricei Van Denburgh, 1895Crotalus pusillus Klauber, 1952Crotalus ravus Cope, 1865Crotalus ruber Cope, 1892Crotalus scutulatus Crotalus simus Latreille, 1801Crotalus stejnegeri Dunn, 1919Crotalus tancitarensis Alvarado-Díaz & Campbell, 2004Crotalus tigris Kennicott 1859Crotalus totonacus Gloyd & Kauffeld, 1940Crotalus transversus Taylor, 1944Crotalus triseriatus Crotalus tzabcan Klauber, 1952Crotalus viridis Crotalus willardi Meek, 1905Mixcoatlus barbouri Mixcoatlus browni Mixcoatlus melanurus Ophryacus undulatus Porthidium dunni Porthidium hespere Porthidium nasutum Porthidium ophryomegas Porthidium yucatanicum
