This video has been recorded during a scientific experiment to investigate the frequency of egg ventilation in shore crabs (Carcinus maenas). Details on the scientific insights can be found here: TheConversationUK (http://bit.ly/297P7Ha) and in Global Change Biology (http://bit.ly/297S8ps).
The female, egg-bearing crab was placed in a plastic bowl with natural sea water and only observed (not harmed) during the experiment. It was returned to the wild afterwards.
