Reptiles are animals with a very wide distribution. Unfortunately 658 species are in danger of extinction and 368 in critical danger of disappearing^[1], according to the most important biodiversity inventory, the Red List of the International Union for Conservation of Nature. In this Green Ecologist article we will introduce you to several species of reptiles that are in danger of extinction and what degree of responsibility we have as humans in the face of this terrible fact.

Blue Iguana (Cyclura lewisi)

The blue iguana, also called Cyclura lewisi, it is endemic to the Cayman Islands. Is found in Danger of extinction, but fortunately their communities are increasing. To date there are already 443 adult specimens thanks to the Blue Iguana Recovery Program started in 2002, made up of national and international efforts collaborating together. The population is expected to have stabilized in three generations.

Marsh Turtle (Glyptemys muhlenbergii)

With the scientific name of Glyptemys muhlenbergii, the marsh turtle is endemic to the United States and is critically endangered. In a period of 20 years, the populations of marsh turtles decreased by 50% and, currently, they occur in 85% in private sites, which means that their loss is due to illegal trade.

Tarzan Chameleon (Calumma tarzan)

The chameleon Tarzan, Calumma tarzan, is named after the Disney character and is a species of lizard endemic to Madagascar, specifically from the eastern region of the island called Alaotra-Mangoro. There are only two populations that are being fragmented by deforestation, leaving little hope for genetic reproduction or recombination, which is why it is currently in critical danger of extinction.

Marbled gecko (Oedodera marmorata)

The Oedodera marmorata, it is a gecko that is severely threatened by nickel mining in New Caledonia, a group of islands in Oceania. They are also often caught for sale, especially in foreign markets, despite the fact that it is legally prohibited. It is characterized by having legs, especially when we speak specifically of its fingers, and very large eyes compared to the rest of the body. The head has neither spines nor ridges and is usually flattened.

Nickel is a metal found in minerals such as nickelin and serves as a conductor of electricity and heat. In fact, New Caledonia is one of the world powers that has deposits for the extraction of nickel. If you want to know more about how mineral extraction affects the environment, take a look at this other post.

Crocodile lizard (Shinisaurus crocodilurus)

Endemic to China and Vietnam, the crocodile lizard or, scientifically speaking, Shinisaurus crocodilurus, has been completely extinct from Hunan province, although globally it is found in Danger of extinction. It is a semi-aquatic species, which if not wetted can go into a state of total inactivity even in the face of any stimulus, which makes it an easy prey.

Mindo horned anole (Anolis proboscis)

The Anole proboscis It is endemic to the cloud forests of Ecuador and it is difficult to find due to its habits associated with the arboreal canopy. For this, It was believed extinct in 1950, until later some specimens were found. However, there is still not enough information to know the trend of its population, although today it is classified as a species in Danger of extinction. As a curiosity, the tail of this lizard measures more than the whole of its body, in addition to having a pointed nasal appendage that differentiates them from the others.

Gray snake (Hemiaspis damelii)

The gray snake, Hemiaspis damelii, lives in Australia and, although it is a relatively common species, its populations are declining and are highly fragmented, so it is currently found in Danger of extinction. This snake is capable of producing venom and has a relatively small size between 50 and 70 centimeters.

Green sea turtle (Chelonia mydas)

The green turtle inhabits the tropical and subtropical belt around the entire planet. It has already become extinct in the Cayman Islands and Mauritius, and it is also estimated that in Israel it has already disappeared. Even so, globally, it is in Danger of extinction. Its main threat begins when it lays the eggs, since, like its meat, it is ingested illegally.

Ganges gharial (Gavialis gangeticus)

Gharials, or Ganges crocodiles, are relatives of crocodiles, but belong to the family of the Gavialidae, where they have very long snouts, adapted to their fish diet. Currently it is another of the reptiles found in critical danger of extinction, mostly in Bangladesh, India and Nepal, but it is extinct in Bhutan, Mynamar and Pakistan. Their populations are increasing thanks to the efforts of multiple sanctuaries and national parks.

Bag turtle (Gopherus flavomarginatus)

This land tortoise is endemic to Mexico and lives in the Chihuahuan desert. Since the Pleistocene, their populations have declined due to climate change, seismic activity that has collapsed their burrows over them, and overexploitation by primitive men. This overhunting has spread to such an extent to this day that the pocket turtle is found in critical danger of extinction.

Causes of endangered reptiles

Next, we are going to mention some of the main causes why reptiles are in danger of extinction:

• Anthropogenic activity: within these, agriculture leads the destructive techniques that modify, or eliminate, the native ecosystems where they live, be they terrestrial or aquatic. Deforestation for wood and pulp, livestock, mining and aquaculture are other economic sectors that fragment their communities.
• Trade- Many reptiles have brightly colored beauty and distant origins, creating great demand for them as pets. They are usually caught to be traded in foreign markets, which is completely illegal, as many of these endangered reptiles are protected.
• Displacement by invasive speciesThey can range from feral cats to ants.
• Residential, tourist and commercial developments: seeking to meet the demands of a growing world population. This fact has created strong pressures on the quality and quantity of the natural resources on which the group depends. reptilia.

In this video from Ecologist Verde we explain the importance of protecting endangered animals.
