This paper deals mostly with recent physiological data on ion transport across the gill tissue and an attempt is made to correlate them with blood osmoregulation and ecological distribution in euryhaline decapods. A particular attention is paid to the gills of the fully euryhaline Chinese crab Eriocheir sinensis . Supporting this ecophysiological approach, there is an important ultrastructural analysis of the gill epithelium under various salinity conditions. The possible part played by the cuticle in ions movements is also considered.
