| Abstract |
Abundance of the invasive and predatory moonsnail Laguncula pulchella was investigated at 10 tidal flats along the coast of Hiroshima, western Japan. They were found from two tidal flats where this species has already been known to occur. The size and density of egg collars of L. pulchella became smaller from 2015 to 2017 but thereafter recovered in 2018. This tendency was common between the two sites, indicating that the population and body size of adult L. pulchella are highly variable among years.
