Abstract: The burrowing behavior and ability of spat with different sizes from 0.5 cm to 3.0 cm were observed in Scapharca broughtonii Sckrenck in a laboratory. It was found that the behavior of the burrowing into the soft sediment was divided into three steps： preparation, burrowing period and terminal period. The burrowing was involved in stretching foot, stacking shell and burrowing into the silt and sand. The spat had various burrowing ability with individual size. The spat with shell length of 0.50 cm has the longest preparation period （ 8.5 rain） and digging time （24 min） with the minimal burrowing rate （ 10% ）. The spat showed significantly shorter preparation period and digging time when it had shell length of 1.50-3.00 cm, whereas the digging rate was increases above 90%. The spat with shell length of 1.50 cm had the shortest digging time, and finished the process within 10 min.
