Monodonta labio (Gastropoda; trochidae) occurs over the whole range of the intertidal zone, but juveniles occur only in the mid intertidal zone. In this study, vertical migration of this snail was investigated by mark-recapture techniques for 1 yr at Amakusa, Japan. Snails migrated vertically throughout the year, but varied with season and size. Generally, juvenile snails (<7 mm in shell width) did not actively migrate. Upward migration was conspicuous only in small snails (7 to 10 mm) in summer. Downward migration was greatest in the larger size classes. Thus, large snails (>=13 mm) gradually migrated downward to the lower zone. Seasonal fluctuations in the vertical distribution pattern of M. labio could be explained by this vertical migration. Possible factors affecting this vertical migration and the adaptive significance of migration in the life history of M. labio are discussed. Seasonal migration . Size . Herbivorous snail .
