The effect of external flow on 3D orientation of a microscopic sessile suspension feeder, Vorticella convallaria

Annals of the New York Academy of Sciences, Volume 1537, Issue 1, Page 51-63, July 2024.
Vorticella are microscopic sessile suspension feeders that live attached to substrates in aquatic environments. They feed using a self‐generated feeding current. Their feeding rate depends on an individual's orientation relative to the substrate and ambient flow. We exposed individuals to varying flow speeds and recorded their 3D orientation.
