Today I took a new video of the stickleback in my lab to use to talk about my work and these amazing fish during public lectures and conference presentations!
What you can see really well in this short little video is the large morphological and behavioural variation of the fish. Despite being similar in age the fish are quite different in body size as well as their colouration. Also pay attention to the spines, you can see individual fish often raising their spines at the moment they feel threatened by my presence.
