Support & help


We regularly receive national and international externship enquiries. As much as we appreciate your interest, we must point out that the exhibition is currently run on a part-time basis. Accordingly, we cannot offer externship supervision during the week, but only on individual days (e.g. weekends). Individual externship enquiries (e.g. as part of an animal keeper training programme) can be submitted to us in consideration of the above -mentioned circumstances.


We would like to support the following projects with your help:

Species conservation: The Serra Grande Center in Brazil, which is dedicated to protecting the giant South American bushmaster.

Humanitarian aid: The Global Snakebite Initiative, which helps victims of venomous bites, especially in developing countries.

Animal welfare: The Reptile Sanctuary Munich e.V., which looks after abandoned, confiscated or surrendered exotic animals throughout Germany.
