Variations in pallial organs and eulatero-frontal cirri in response to high particulate matter concentrations in the oyster Crassostrea gigas
Variations in gill, palp, and adductor muscle areas and in the length and spacing of eulatero-frontal cirri (EFC) were investigated in specimens of the Japanese oyster (Crassostrea gigas) within the same bay in two nearby sites (15 km) differing in turbidity. Significant variations occurred on a sma...

Variations in gill, palp, and adductor muscle areas and in the length and spacing of eulatero-frontal cirri (EFC) were investigated in specimens of the Japanese oyster (Crassostrea gigas) within the same bay in two nearby sites (15 km) differing in turbidity. Significant variations occurred on a small geographical scale. In particular, individuals from the higher turbidity zone had smaller gills and larger labial palps. For a standard oyster (1 g dry body weight), gill area was 25% larger in oysters from the low-turbidity zone, while palp area was 66% larger in oysters from the high-turbidity zone. No difference was observed for total adductor muscle area.
