INTERINDIVIDUAL TRAIL FOLLOWING BY THE INTERTIDAL PATELLID LIMPET CELLANA TOREUMA

摘要

Interindividual trail following by the patellid limpet Cellana toreuma was studied by field observations for more than ten successive days in the non-reproductive period. This behaviour was more frequent during spring tides than neap tides, when the limpets were moving longer distances in response to greater tidal amplitudes. Small individuals performed this behaviour with longer distances and higher frequencies than did larger individuals. Path analysis revealed that total distance moved during foraging excursions and mean resting site height had direct and indirect positive effects on the frequency of the interindividual trail following, respectively, and shell length and frequency of intraindividual trail following exerted a direct, negative effect.
