Where do reptiles live in the world

Castilian snake

Reptiles inhabiting El Salvador include snakes, lizards, crocodiles and turtles. El Salvador has a herpetofauna that includes 141 species of reptiles,[1] which are grouped into 3 orders and 26 families.

The emydids (Emydidae) are a family of carnivorous aquatic and semi-aquatic turtles. They live most of the time in ponds, reservoirs and rivers, going to land when they have to find suitable places to lay their eggs. This family is made up of 10 genera containing more than 50 species, four of which occur in El Salvador.

Alligatoridae (Alligatoridae) is a family of crocodilian sauropsids (reptiles) native to the Americas (with the exception of one species), commonly known as alligators, caimans and caimans. It includes the extant genera Alligator, Caiman, Melanosuchus and Paleosuchus, as well as numerous extinct genera. Of the 7 species that inhabit the Americas, one occurs in El Salvador.

The Anguids (Aguidae), popularly known as glass lizards, are a family of lacertid reptiles characterized by atrophy of the legs, although they are not directly related to snakes; it is, therefore, a remarkable case of evolutionary convergence. The distribution of Anguidae covers the Old and New World. It is absent only from Australia. Most species are terrestrial and live in leaf litter on the forest floor. The Anguid family is divided into three subfamilies, eight genera and contains 94 species, of which 5 occur in El Salvador.

The chelidids (Chelydridae) are a family of freshwater turtles consisting of seven extinct genera and two extant genera, both native to the Americas. The extant genera are the snapping turtles (Chelydra) with three species, and the alligator snapping turtles (Macrochelys) with only one species. Of the total of four extant species, one occurs in Belize.

The emydids (Emydidae) are a family of carnivorous aquatic and semi-aquatic turtles. They live most of the time in ponds, reservoirs and rivers, going to land when they have to find suitable laying sites. This family is made up of 10 genera containing more than 50 species. Three of them occur in Belize.

Tropical herping

In the world there are more than 50 species known as mangrove, Mexico is among the five countries with the greatest extension of mangroves, distributed in the 17 coastal states of the country, which represents 5 percent of the world's total coverage.

Mexico's four mangrove species are: red mangrove (Rhizophora mangle), white mangrove (Laguncularia racemosa), mangrove prieto (Avicennia germinans) and mangrove botoncillo (Conocarpus erectus).

Well-conserved mangroves have a large amount of permanent biomass. Biomass is all matter that comes from life, such as leaf litter, sludge, wood, among others; because of this, they store large amounts of carbon.

This ecosystem provides very important environmental services for humans, they function as natural barriers that stop erosion, help maintain sand on beaches, control flooding, protect against hurricanes and storms, capture carbon and generate nutrients for other ecosystems.

In Venezuela there are chameleons

The word reptile is almost always associated with filthy and cruel beasts, despite the fact that among them there are admirable creatures, both for the elegance of their forms and for the variety of their colors. The fate of reptiles has changed in the course of time and after having dominated the earth, the air and the waters, today they lead an obscure life and only a few vigorous branches of what was a great evolutionary trunk persist.

The respiratory system also underwent adaptations. As the surface of the skin became thicker, harder and dead, gases could no longer pass through it, so that gas exchange was necessarily restricted to the lungs.

Although most reptiles exhibit remarkable evolutionary modifications in their limbs, one group in particular, the Ophidia, lost their limbs, and to move they have to rely on basic undulatory movements of the spine, but in snakes there are many different forms of movement such as lateral twisting, leaping, concertina, etc., all variations of sequential condulations of muscle mass.
