Abstract: | The two clingfish species studied occupied similar habitats but occurred at different depths. When compared with the subtidal species Lepadogaster candollei , the intertidal species Lepadogaster l. purpurea was less active, spent more time in shelters, visited fewer shelters, showed more site fidelity, and spent less time swimming. Feeding, swimming, and agonistic behaviours were performed mainly in close contact with the substrate in this species. It is hypothesized that these contrasts in behaviour may have evolved under different levels of turbulence. |
