Welcome to Atelopus.com

The Atelopus species live in the American tropics. During the last 20 years the populations have declined over most of their distribution range. In the last 10 years several well studied populations that have gone extinct from nature, for example the golden frog (Atelopus zeteki) that we chose to use in our logo. There is a combination of reasons for the disappearing of these frogs but the main reasons are the loss of habitat, disease, pesticides and climate change. It has been told that of the 113 harlequin frog species of Central and South America, at least 30 have vanished in the last 20 years. Also 81 percent of the adequately studied species are in decline because of the above mentioned reasons. Besides all this bad news it should also be told that there are probably many more species of Atelopus that haven’t been discovered and/or described until this day.We want to try and expose a little bit more about these wonderful forest-dwelling neotropical toads, called harlequin frogs, to the world. By spreading more information about them we might hopefully be part in helping the world to be aware of this genus of species that is disappearing. Letting people know more about these animals might be a step in getting help for them to survive in the wild.We hope you’ll enjoy the photos and information on this website.

 


Monitoring Atelopus

Atelopus Pulcher
Monitored by:
Dennis Nilsson (Sweden), Remco Stuster (Netherlands), Josh Richards (Peru).
Date: July 21, 2019
Location: Cordillera Escalera, Peru
Population status: Critically Endangered

One female individual found.



Atelopus Pulcher
Monitored by: Josh Richards (Peru)
Date: April 2, 2018
Location: Cordillera Escalera, Peru
Population status: Critically Endangered

Josh lives in Tarapoto Peru and have seen Atelopus pulcher regularly in the Cordillera Escalera. In the past month, they have seen 6 animals and he saw a 7th animal late last year. The population seems to be slowly coming back. We all hope he is right.

Our Motivation

The Atelopus are disappearing rapidly in Latin America and we, in the role of frog-lovers, would hate to see them disappear from their natural habitat. We have build this website to get more attention for these lovely beings and we hope to get more people to recognize this problem. Let's hope this website is not the last place where you can see the Atelopus species in the future.

 

Monitoring Atelopus

It's interesting to know about how the status is of the diffrent Atelopus populations. If you have been in a population recently or at least later then published here, please tell us. We will publish the recieved information, photos or just the latest seen list.
