Bilaterian facility – the Hejnol group

The Hejnol group cultures a broad range of animal taxa which are used for studying the evolution and development of animal diversity by using morphological and molecular methods.

Our group studies a broad range of animal taxa using morphological, molecular and genomic tools to understand the evolution and development of animal organ systems

In the animal facility there are two large incubators, one smaller algae incubator at 16°C and one 500 litre seawater aquarium system. The room is kept at a continuous 22°C and there is a 14/10 light/dark cycle for the room, all incubators and the aquarium. The maintenance of the room, equipment and organisms is taken care of by fulltime animal technician.  

Continuous cultures are maintained of the following animals:

In addition to the continuous cultures we also collect and keep for shorter periods species of Priapulida (Priapulus caudatus), Brachiopoda (Novocrania anomalies) and Nemertodermatida (Meara stichopi).
