(7) Brazilian turtle (Chrysemys picta)
Widely distributed, it is the most widespread freshwater turtle in North America, commonly found in wetlands and lakes. It has red stripes along the edge of its shell and can tolerate low temperatures.
(8) Mexican parrot snake (Leptophis mexicanus)
It has a slender body, is bright green, and camouflages itself in dense vegetation to prey on frogs and toads. It is distributed from southeastern Mexico to Costa Rica.
(9) Cross-volcanic rattlesnake (Crotalus triseriatus)
It is found only in the Transverse Mountains of Mexico, in forest and grassland ecosystems, and has a distinctive rattle ring on its tail, which is one of the national symbols.
(10) Box turtle (Terrapene carolina)
Native to Mexico and the United States, it can retract its entire body into its shell for self-protection. It is terrestrial, often digging burrows in soft soil.
(11) Mexican western coral snake (Micrurus distans)
It has ring-shaped red, black, and white markings on its body and is extremely venomous. It is protected under Mexican law to prevent overhunting and habitat destruction.
(12) Lilac turtle (Lepidochelys kempii)
The sea turtle with the narrowest global distribution, it mainly lives along the Gulf Coast and is a critically endangered species, occasionally migrating to the Atlantic coast.
(13) Spectacled Caiman (Caiman crocodilus)
Distributed from southern Mexico to northern South America, it is of medium size and is named for its arched eyes that resemble glasses.
(14) Yucatan blind snake (Amerotyphlops microstomus)
It has a limited distribution only on the Yucatan Peninsula, is terrestrial, has extremely degenerated eyes, and is commonly found in dry and wet forests and degraded areas.
(15) Desert Horned Lizard (Phrynosoma platyrhinos)
Distributed in the deserts of northern Mexico and the southern United States, it is covered with small thorns and has a distinctive horn-like protrusion on its head, making it adept at camouflage.

3. Ecological Roles of Reptiles in Mexico
Reptiles are an important part of Mexico's ecosystem. They participate in controlling pest populations, maintaining food chain stability, and providing food sources for birds of prey and large mammals. In addition, the presence of some reptiles also promotes seed dispersal and maintains wetland ecological health.
