Abstract: Metal contamination of the environment is a serious subject around worldwide. The effect of heavy metals on survival rate of horseshoe crab trilobite larvae to cadmium exposure in 96 hours was assessed in this study. This study was conducted to determine the survival rate for continuous exposure of Cd on Tachypleus gigas trilobite larvae. Metals accumulation in Tgigas trilobite larvae also was measured. There is no mortality occurred in preliminary experiment with low of cadmium concentration and the same situation also happened in exposure of Tgigas trilobite larvae to medium concentration of Cd for 96 hours. The continuous exposure ofto high concentration of Cd (100 mg/L) gave the mortality of Tgigas trilobite larvae. There were mortality occur in 60 and 80 mg/L of Cd concentration after 96 hours of exposure. Metal accumulation in Tgigas trilobite larvae tissue for exposure to 100 mg/L of Cd concentration is highest which is 0.5141 µgig compared to others.
