- Opportunistic suspension feeding in the intertidal gastropod Olivella columellaris and its implications for the regulation of tidal migrations Aaron P Morse Winfried S Peters Ciencias de la Tierra tidal migration endogenous clock Olivella columellaris sandy beach intertidal zone underwater sailing locomotion The gastropod Olivella columellaris inhabits sandy beaches of the Tr opical East Pacific. These snails perform tidal migrations for continuous suspension feeding in the moving backwash zone, possib ly controlled by an endogenous circatidal clock. However, O. columellaris readily modifies its circatidal behavior, for example when flow channels develop below natural and artificial tide pools at ebb tide. Suspension feeding continues in such channels while water is running, dela ying tidal migration. Su ch behavioral plasti city questions the s ignificance of endogenous rhythms for the regula tion of tidal migrations in O. columellaris . 2016 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48049436005 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4 Vol.42
