Abstract

1. Mechanical and visual stimuli associated with surface waves were separated into their two components. 2. Unfed leeches responded to the mechanical component of artificially generated surface waves by swimming towards their source. 3. Leeches also responded to and orientated towards the source of the waves using visual cues derived from the same surface waves. 4. Visual stimuli elicited fewer and less accurate responses.
