Summary edit
Japanese basket clams settle at the mouths of rivers in brackish water. During low tide, people are able to see them in tidal flats and collect them for food. Their shells are roughly 30-35mm and are reddish-brown while young, turning black as they mature. Their shells are glossy and have a tendency to grow concentric circles from their base, similar to Corbicula fluminea. The inside of their shells is purple when they are young and becomes white as they mature. Their reproduction is based on gonochorism.
Culinary Use edit
Japan edit
In Japan, the clam is usually called shijimi, though this technically refers to the Corbicula genus in general. The more precise name is yamato-shijimi ("Japanese corbicula"). Shijimi and asari, (Lajonkairia lajonkairii) are two of the most common clams used in soups and tsukudani (simmered seafood).[3]
