migratory

“To cope with daily variation of environmental parameters, talitrids evolved a migratory behaviour, synchronized with tidal and nictemeral cycles, that enable them to locate the suitable patches of habitat on the shore (Pardi and Ercolini 1986).”

“Even among migratory species, only a few (Aglaura hemistoma, Abylopsis tetragona eudoxids, Beroe sp., Thalia democratica, Salpa fusiformis) crossed the thermocline and reached the bottom layer.”
