## Turtles (Testudines)

[edit]

Mexico has a total of 54 species of turtle, grouped into 7 families and 20 genera.[2] Among them, there are 6 marine species, almost all of them in danger of extinction.

### Cheloniidae

[edit]

Chelonia mydas Eretmochelys imbricata

Order: Testudines · Family: Cheloniidae

Sea turtles (Cheloniidae) 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.

## Crocodilians (Crocodylia)

[edit]

### Crocodylidae

[edit]

Crocodylus acutus Crocodylus moreletii

Order: Crocodylia · Family: Crocodylidae

Crocodiles (Crocodylidae) 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 VU
* Crocodylus moreletii Duméril & Bocourt, 1851

### Alligatoridae

## Lizards (Squamata - suborders Dibamidae, Laterata, Gekkota, Iguania, Anguimorpha, Scincomorpha)

[edit]

### Anguidae

[edit]

Order: Squamata · Family: Anguidae

Anguids (Anguidae) 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 (one extinct), 10 non-extinct genera, and contains 94 species. In Mexico there are 50 species.[3]

Order: Squamata · Family: Gekkonidae

Geconids or geckos (Gekkonidae) are a family of scaly sauropsids (reptiles), 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.

Iguanids can reach lengths that vary between 14 cm (5.5 in) and 200 cm (79 in). 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.

Order: Squamata · Family: Dactyloidae

Dactyloidae is a family of lizards commonly known as anoles. They are small lizards native to the American continent, from the southeastern United States, the Caribbean, Central America to South America. They are characterized by having a parietal eye; most have a greenish color and a very long tail. Adult males exhibit a brightly colored fold of skin in the gular region. They feed on insects, mainly crickets. The majority is arboreal. They are very territorial animals. There are around 390 species recognized on the American continent, and 55 species that occur in Mexico.

### Gymnophthalmidae

[edit]

Order: Squamata · Family: Iguanidae

Gymnophthalmidae is a family of lizards commonly known as microtheids. They have transparent lower eyelids that allow them to see with their eyes closed. They are related to the tiiids, but due to their smooth scales they are more similar to scincids. They are generally small lizards, and many species have reduced limbs. They live in a wide variety of habitats - including desert, mountains, and rainforest - throughout Central and South America. They generally inhabit the forest floor or humid areas associated with tropical forests. They are nocturnal animals or are active intermittently during the day. They feed mainly on insects and other invertebrates. All species are oviparous. The family is made up of more than 240 species grouped into 40 genera. A species occurs in Mexico.

It can reach a length of 157 cm (62 in), but usually measures 77 to 100 cm (30 to 39 in). 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.

Lampropeltis triangulum Leptophis ahaetulla Oxybelis aeneus Oxybelis fulgidus Spilotes pullatus Elaphe flavirufa Pseustes poecilonotus Drymobius margaritiferus

Order: Squamata · Family: Colubridae

The colubrids (Colubridæ) 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 (or possess venom that has no notable effect on humans), 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.[6]

### Elapidae

[edit]

Order: Squamata · Family: Elapidae

Hydrophis platurus

Elapids (Elapidae) 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 18 cm (7.1 in) (Drysdalia) to more than 5 m (16 ft) (Ophiophagus) 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.

### Viperidae

[edit]

Bothrops asper Agkistrodon bilineatus Bothriechis schlegelii Porthidium nasutum

Order: Squamata · Family: Viperidae

The viperids (Viperidae) 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.
