Growth of Olivella fulgurata (Gastropoda: Olividae) in Sagami Bay, Miura Peninsula, central Japan

Abstract

Olivella fulgurata (A. Adams & Reeve, 1850) (Gastropoda: Olividae) is a common inhabitant of exposed sandy beaches in the southern part of the Boso Peninsula, Japan. The population biology of this species on the eastern coast of Sagami Bay, Miura Peninsula, Central Japan, was studied from January 2008 to June 2009. Newly recruited juveniles of O. fulgurata appeared from May to June, and grew rapidly thereafter. The lifespan of O. fulgurata was estimated to be about 1 year.
