抄録: In gastropods, there are two typical attachment manners, namely foot attachment and mucous attachment. Some littorinids are known to minimize heat stress by "tip-lip" attachment, which is the manner to attach with dried mucous thread to minimize contact with the hot substratum. Spatial variation on the frequency of "tip-lip" attachment was examined in the periwinkle, Nodilittorina radiata at two rocky coasts in Usa-cho, Kochi, Japan. Shell length, direction of attachment site and height of attachment site might not affect the attachment manners. Height of rocks was negatively correlated with the frequency of "tip-lip" attachment. These results suggest two possibilities: snails acquire lower thermal stress on higher rocks and/or snails exhibit "tip-lip" attachment more frequently on horizontal rocks than on vertical rocks.
