Concerted tentacle flexions In the majority of hydra investigated, an Artemia placed on a single tentacle was engulfed within 80-100 seconds. However, concert activity initiated with the first tentacle movements, continues long after the prey has been swallowed (Fig. 2, upper graph). Only 15-20 minutes after the prey has been engulfed does the concert frequency decrease to the pre-feeding level.
