Twycross Zoo - Follow Your Heart

Opening Times: 10am - 5pm

Ape Heart Project

What is the Ape Heart Project?

Twycross Zoo is leading research into heart diseases in great apes.

Heart diseases are often reported as a significant cause of death among great apes (chimpanzees, bonobos, gorillas and orangutans), similar to us, humans. However, our understanding about these conditions and consequently our abilities to treat and prevent them are limited.

Twycross Zoo and its partners, including the University of Nottingham and the University of Birmingham are leading the way in an exciting project. An international team of veterinarians, cardiologists and researchers are working hard to better understand great ape heart diseases. This work will help us to provide even better care not only for our animals but all great apes across Europe and beyond.

This project is part of a European Association of Zoos and Aquaria (EAZA) Great Ape Taxon Advisory Group endorsed initiative striving to develop a collaborative and co-operative approach to the investigation of heart diseases among the European great ape population.
