What endemic species are there in Mexico

The number of species that exist on our planet is indisputable. However, they are not all everywhere, which makes them even more special. This time we want to delve into the endemic fauna that exists in the region of Mexico, one of the 12 countries with the greatest biodiversity in the world.

Location and main characteristics of Mexico

Mexico or, rather, the United Mexican States , is a country that is located in the southern part of North America. With an area of ​​1,964,375 km 2, Mexico is the fourteenth largest country in the world and the third in Latin America. It is bounded by its coasts bathed by the Pacific Ocean to the west and the Gulf of Mexico together with the Caribbean Sea to the east. As for its inhabitants, it is the eleventh most populous country, with a population of approximately 124 million people in 2017.

Its relief is very rugged and has a large number of volcanoes. In addition, there are the Madre Oriental and Madre Occidental mountain ranges, which are an extension of the Rocky Mountains.

Mexico has a very diverse climatic variety where the average temperature is around 19ºC, although we can find both cold climates in the mountainous areas and very hot climates in the areas near its coasts. The country is also divided into two very different areas by the Tropic of Cancer: an area with a tropical climate and another with a more temperate climate.

What are endemic species

Before continuing with the article we must make a little parenthesis. Do you know what endemic species are ? An endemic species is one that refers to a species whose distribution is restricted to a specific geographic location and which is not naturally found in other regions of the world.

However, an endemism does not specify how restricted it is. By this we mean that the scale is very variable, an endemism can be its own from a mountain to an island or a continent. Similarly, here we are referring to species, but you can also refer to other larger groups such as genera or families. With all this, the general thing is that it is indicated which taxon we are referring to (species, subspecies, family …) and from where.
