The swarming behaviors of Vorticella

Abstract

Two Vorticella species undergo a synchronous transition from sessile zooids to motile telotrochs, which swarm enveloped in secreted mucus, subsequently forming dense aggregations on substrates and reverting to the zooid form. This cyclical process recurs on a daily basis. Each species exhibits a unique mode of swarming behavior. We hypothesize that these behaviors may serve to facilitate efficient feeding while concurrently acting as a mechanism for predator avoidance.
