And the next trip of Atheris will be … Mexico! Mexico is simply one of the countries with the greatest diversity of reptiles in the world. Realize, there are over 900 species of reptiles in Mexico … including 42 species of Crotales, incredible but true! See you soon, for a review of our herptrip on www.atheris.earth!
Here we are, for the fourth year in a row, visiting Morocco. This country is a paradise for reptile fans! As every year, our friend Abdou has joined us. We are accompanied by Dylan, Miguel, Marion and Jean, four members of the association, who we hope will not be disappointed with the trip! Our goal is to contribute to the improvement of knowledge in progress in this country (study of the distribution of species, genetic samples, etc). We spent a week exploring different types of habitats to produce presence data and rise our photo and video database. The research is also done in tanks, many in these arid areas, and where animals often fall. This is an opportunity to save these animals while making some unpublished observations.
Costa Rica is a small country by its size: 51 000 km². On the other hand, in terms of biodiversity, it is simply remarkable. Amphibians and Reptiles alone, we are talking about more than 400 species!
In addition, Costa Rica has focused on green tourism and the preservation of biodiversity. The preserved natural areas are still numerous, and everything is made to welcome naturalists curious about the tropical fauna. We had already visited this country in the past, and it was urgent to return there, to discover the most remarkable species of the country.
It was the priority target of our herp trip in Uganda: the famous African Hairy Bush Viper Atheris hispida, the arboreal viper with dragon look! This species lives in the lowest primary rainforests in Uganda. Impacted by deforestation, the country’s natural areas are particularly fragmented. The places where inhabit this species are reduced year by year under the pressure of agriculture and the production of exotic wood. Today we are all responsible. Action is urgently needed, so please reduce our consumption to preserve biodiversity.
The next trip of Atheris organization is a “back to the source” for some of us. Ten years later, we are back in Costa Rica.
Costa Rica is probably the most visited Central American country for naturalist travel. It’s normal: the biodiversity in fauna and flora is simply exceptional, and the environment is largely preserved there. We hope to meet many people there … See you in November for the report!
Atheris’s last trip in Morocco allowed the observation of one of the most remarkable species of the country: the Sahara Sand Viper Cerastes vipera. This species is strictly restricted in sandy environments. It is perfectly adapted for life in the sand, as suggested by the position of its eyes, oriented at the top of the head. Here is a short video which present the species. (more…)
A small trip in the western Pyrenees allowed the observation of a rare behavior: a fight between two males of Aesculapian Snakes, obviously on the same territory. A scene that we could immortalize! (more…)
Pseudocerastes persicus and Pseudocerastes urarachnoides are two of the three species of the genus Pseudocerastes which occur in Iran. Our naturalist trip allowed us to observe, on the same place and during the same day, these two species. A wonderful example of sympatry!
This observation is the subject of a paper published in the journal Herpetology Notes. Do not hesitate to read the article!

During our last Atheris trip 2017 in Morocco, we have made a rare observation: the gloved cat, Felis lybica. This species is the origin of domestic cats. This observation is described in an article by www.ecologie.ma.
