Sanguinolaria rostrata is a deep site-burrowing bivalve commonly found in the southwest coastal waters of Taiwan. It has a long siphon extending to the surface. It is reported that exposed S. rostrata dies in few days without silt. However trussing it up rubber bands or cut off the hinge, it can survive for over one month in the laboratory. In this study the relation of shell closing and mortality for S. rostrata were examined and compared with the hard clam Meretrix lusoria in the similar environments. The size of adductor muscle and its ratio to the shell size, the strength of shell closing and the tissue structure of adductor muscle were examined. The quantities of fructose 2,6- biphosphate, an intermediate of glycolysis, in the adductor muscle of S. rostrata were determined. The results indicated that the average strength of closing shell for S. rostrata was 36.65% and for M. lusoria was 41.19%. The trends of tropic shell closing strength and the size of adductor muscle as well as shell closing strength and the adductor muscle wet weight were the same for the two species. The ranges of strength for muscle closing among S. rostrata of different sizes were smaller than those of M. lusoria. The average ratio of the adductor muscle microfiber to muscle was 55.6¢Mfor S. rostrata and 83.2¢M for M. lusoria. Therefore, the adductor muscle of S. rostrata is looser to M. lusoria. The concentration of fructose 2,6- biphosphate fluctuated widely to the unclamped S. rostrata in the first 6 hours and the concentration reached 7.58£gmole/mg at most. The concentration did not rise between 6 and 24 hours, indicating that unclamped S. rostrata consumed energy within the first 6 hours, then showed no sign of consuming energy.
