抄録

A field study was conducted on the spatial distribution and individual activity range of the potamidid gastropod Cerithidea rhizophorarum in the estuary of the Kushida River, Mie Prefecture, central Japan. Large snails occurred widely in various habitat conditions in and around the salt marsh, whereas small snails were confined to the non-vegetated area, especially a puddle, around the salt marsh. Cross-shore distribution of the snails showed peak abundance in the lower vegetated to upper non-vegetated area in all four seasons, but small snails occurred only in the non-vegetated area. Reproductive activities such as mounting and spawning were observed in both the lower vegetated and upper non-vegetated areas. A tracking survey of marked large snails for 72 days revealed that the individual activity range was confined to 1-3 m in the vegetated area and 2-5 m in the non-vegetated area.
