潮間帯弁鰓類の消化活動(総説)

抄録

This review article gave an outline of the summary account on the structures of feeding and digestive organs, on the intracellular and extracellular digestion, and on the digestive rythms in the intertidal and subtidal lamellibranch molluscs. The crystalline style is dissolved as the tide ebbs and rapidly reformed when the tide returns. The processes of normal or holding, absorption and digestion, disintegration, and of reconstitution of the digestive tubules are organized in distinct phases throughout the digestive diverticula. In some genera, tidal cycle related twelve hours or twenty four hours cycles are shown in feeding and digesting processes. The cycles seemed to have adaptive significance to habitat condition and mode of life of each species.
