This paper analyzed the effects of water temperature, salinity and particle size of the substratum on the burrowing behaviors of the three Veneroid bivalves, <i>Pseudocardium sachalinensis, Mactra chinensis</i>, and <i>Ruditapes philippinarum</i>. The starting time for burrowing behavior (STBB) and mean burrowing velocity (MBV) of the three bivales in 15-25°C tended to be more rapid than those in 5-1O°C. In 5-10°C, STBB and MBV of <i>P. sachalinensis</i> were the most rapid, and the burying depth of this species in 5-10°C was deeper than that in 15-25°C. In <i>R. philippinarum</i>, the ranges of optimum salinity and particle size for burrowing were wide compared with the other species. It was concluded that the burrowing behaviors of <i>P. sachalinensis</i> and <i>R. philippinarum</i> are well adapted to the dynamic swash conditions in high latitudes and to sites with fresh water, fluctuation of water temperature and low sorting sediment.
