Infection by parasites disturbs flight behaviour in shoals of fish

Shoal behaviour in fish is an important strategy for them to safeguard their survival, as is the case for other animals too. Certain parasites are able to manipulate this strategy. Biologists at Münster University have discovered that infected individual fish disturb the transmission of flight behaviour and, as a result, increase not only their own risk of being eaten, but also that of other – non-infected – members of the group. The results of the study have been published in the journal “Proceedings of the Royal Society”.
