One hundred polyps were sampled, and their contents studied, every 2 h over three 24-h cycles. The overlying Zooplankton was simultaneously sampled in order to compare the prey with the available plankton. The maximum residence time of the prey in the coelenteron was estimated to be ≈ 5 h. Eudendrium is carnivorous, each polyp taking an estimated mean of 4.3 prey items · day-1. Thirty-nine percent of the polyps had at least one prey item at all times. Prey items had smaller dimensions than the polyp, but long thin organisms were sometimes taken. The number of captured items was strongly correlated with Zooplankton density, suggesting that E. racemosum is an opportunist with no innate diurnal or other feeding rhythm. Estimated captures of E. racemosum are of 100000 prey items · m-2· day-1 in the study area. Therefore, benthic hydroids may exert considerable effects on local plankton populations and play an important rôle in the transfer of energy from the plankton to the benthos. © 1988 2022-04-06T12:00:03Z 2022-04-06T12:00:03Z 1988-03 2022-04-06T12:00:03Z artículo http://purl.org/coar/resource_type/c_6501 issn: 0022-0981 Journal of Experimental Marine Biology and Ecology 115(3): 281-293 (1988) http://hdl.handle.net/10261/266461 10.1016/0022-0981(88)90160-8 https://doi.org/10.1016/0022-0981(88)90160-8 Sí none Elsevier
