No more snakes in the house!

On the other hand, amphibians are not classified as aquatic animals because they do not need a habitat for aquatic life. Most amphibians begin their life stage in the water, like tadpoles, but as they grow older they have a terrestrial life that returns to the water only to mate.

Terrestrial animals are the animals that live mainly on land such as dogs, lions, lizards, etc. Their physiognomy is adapted to terrestrial life and, depending on their biome, they can crawl, jump, walk, etc.

There are characteristics by which we recognize animals: they are multicellular, they obtain energy for life by eating other organisms, and they can move and sense their environment, but these do not define an animal.

There are many different types of animals and all animals in the world belong to one of them. For ease of organization, animals can be divided into two major groups: vertebrate and invertebrate animals.

Within the two main groups of animals mentioned above are the types of animals grouped into: amphibians, arachnids, birds, felines, insects, mammals, fish and reptiles:

Reptiles that inhabit 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.

Las tortugas existen desde antes de los dinosaurios, apareciendo hace unos 200 millones de años en el Periodo Triásico. Hay unas 250 especies de tortugas y pertenecen al orden Testudines. Viven dentro de caparazones duros llamados plastrón (abajo) y caparazón (arriba) y algunas se encierran en ellos para protegerse. Su piel expuesta es seca y escamosa. Las tortugas no tienen dientes, pero algunas tienen un pico pronunciado con bordes afilados para morder. La mayoría de las tortugas pasan horas tomando el sol, ya que su temperatura corporal interna se controla mediante el comportamiento. Esto significa que, para mantener una temperatura corporal algo constante, las tortugas deben desplazarse a donde haya una fuente de calor.

Existen unas 2.700 especies de serpientes en todos los continentes excepto en la Antártida. Las pruebas fósiles se remontan al Cretácico, hace unos 130 millones de años, pero aún no existe ningún vínculo definitivo con estos antepasados primitivos. Las serpientes se distinguen por carecer de extremidades, apéndices auriculares externos y párpados. Su cuerpo musculoso está cubierto de escamas lisas protectoras, con una única hilera de escamas especializadas a lo largo de la parte inferior del cuerpo que les permiten desplazarse por los terrenos más accidentados o a través del agua.

Toy Dinosaur Egg growing in Water

Female Nile crocodiles lay their eggs in a buried nest, and open it when they hear squeaks coming from it. The sex of the hatchlings depends on the temperature of the nest, not genetics.Photo by Michael Nichols5 September 2010

The oceans, especially those that formed new, shallow inland, were teeming with abundant life. At the top of the food chain were long-necked plesiosaurs, giant marine crocodiles, sharks and rays. Fish-like ichthyosaurs, squid-like cephalopods and ammonoids with their spiral-shaped shells. Coral reefs grew in the warm waters and sponges, snails and mollusks grew without difficulty. Plankton floated free, microscopic and could make part of the ocean red.

On land, dinosaurs were making their mark, literally. The herbivorous sauropod Brachiosaurus stood 16 meters tall, was about 26 meters long and weighed more than 80 tons. Diplodocus, another sauropod, was about 27 meters long. The sheer size of these dinosaurs may have deterred the Allosaurus, a hulking, carnivorous dinosaur that walked on two powerful legs, from attacking them. But Allosaurus and other fleet-footed carnivores, such as coelurosaurs, might have been successful a time or two. Other prey could be the huge armored stegosaurs.
