Internal characteristics of reptiles

This list of reptiles of Venezuela includes 405 species of reptiles that are recorded as inhabiting Venezuela.[1] The listing is based on The Reptile Database.[1] The reptiles of Venezuela are grouped into 3 orders and 30 families, and include snakes, lizards, crocodiles and turtles.

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. Two of them occur in Venezuela.

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, 3 occur in Venezuela.

What are reptiles and what are their characteristics?

Reptiles are vertebrate animals that are characterized by crawling. That is, they crawl along the ground, like snakes, crocodiles, lizards or turtles. This is because they originally lived in aquatic environments. Evolution has led them to adapt completely to terrestrial life.

What characteristics does an animal need to be classified as a reptile?

Reptiles are animals that are characterized by their skin, covered with scales or by a protective shell as in the case of turtles, and also by their very particular way of moving: dragging their belly along the surface.

What is the importance of reptiles?

Based on the available literature on the role that amphibians and reptiles play in neotropical ecosystems, it was found that these groups participate in processes such as energy flow, nutrient cycling, dispersal, pollination and pathogen regulation.

Cresta

Los mamíferos son animales asombrosamente diversos. Viven en casi todos los hábitats de la Tierra -incluidos los fondos marinos, las selvas tropicales y los desiertos- y su tamaño oscila entre las musarañas de un gramo y las ballenas de 200 toneladas. ¿Qué es exactamente lo que hace que un mamífero sea un mamífero y no un reptil, un ave o un pez? Los mamíferos se distinguen de los demás vertebrados por ocho características principales, que van desde el pelo hasta el corazón de cuatro cámaras.

A todos los mamíferos les crece pelo en algunas partes del cuerpo al menos durante alguna etapa de su ciclo vital. El pelo de los mamíferos puede adoptar diversas formas, como pelaje espeso, largos bigotes, púas defensivas e incluso cuernos. El pelo cumple varias funciones: aislamiento contra el frío, protección de la piel delicada, camuflaje contra depredadores (como en cebras y jirafas) y retroalimentación sensorial (como los sensibles bigotes del gato doméstico). En general, la presencia de pelo va unida a un metabolismo de sangre caliente.

¿Qué ocurre con los mamíferos que no tienen vello corporal visible, como las ballenas? Muchas especies, como las ballenas y los delfines, tienen poco pelo durante las primeras etapas de su desarrollo, mientras que otras conservan mechones de pelo en la barbilla o en el labio superior.

Cephalic scales

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.

secondary species are considered of medium sensitivity, because they allow the development of species included in the Data Deficient category (Rhinella margaritifer, Rhinella dapsilis and Rhinella festae) and Appendix II of the CITES (Ameerega bilinguis, Ameerega hahneli, Allobates femoralis, Ranitomeya duellmani, Tupinambis teguixin).

of species included under Insufficient Data category (Rhinella margaritifer, Rhinella dapsilis and Rhinella festae) and Appendix II of the CITES (Ameerega bilinguis, Ameerega hahneli, Allobates femoralis, Ranitomeya duellmani, Tupinambis teguixin).

Through an agreement between the two parties, the Rescue Center became officially responsible for the management and disposal of the confiscated fauna. Currently, the center operates with a veterinary medical advisor specializing in wildlife, a project manager (biologist), a staff veterinarian, and an assistant for feeding and
