Invertebrates such as polychaeta, cephalopoda, gastropoda, echinodermata and actiniaria were also intermittently found in them. They intensively fed all the year found (monthly feeding rate of over 80%). The main food items wereAlpheus japonica, Alpheus distinguendus. Oratosquilla oratoria, Eucrate crenata andCarcinoplax vestitus, etc. In summer and autumn, the portion of bivalvia such asCultellus attenuatus andMusculus senhousei increased steadily.
