摘      要：In Inderasabah(southeast Sabah),tri-spine horseshoe crab Tachypleus tridentatus was observed for their locomotion activity using data loggers from September to November in 2015.A female with acceleration and depth-temperature loggers and five males with acceleration loggers were recaptured between 10 and 49 days after their *** the record of 194 activity days that involve all six ***,four horseshoe crabs,including the female,were active throughout the 24.0 h cycle,whereas the activity of the remaining two males was consistent with the 12.4 h *** the 40-day recording,three horseshoe crabs,including the female,were primarily active around the new moon and full moon,but they were dormant around the first and third quarter moon *** female spent much time in shallow shores(depth0.3 m)during the new moon and full *** result indicated that the female attempted to spawn in a minimum of three spring tide periods while lingering in the ***,after spawning,the female spent time foraging in shallow water(depth 0.3–18 m).As for the two male individuals,their activity was consistent with semi-lunar ***,both of them were in *** addition,a solitary male individual was active only during the first and third quarter moon *** activity recording,all the *** in Inderasabah was active during daytime and *** result was contrary to *** activity cycles in western Japan,where the species was found to be primarily ***,the regional differences in activity cycles for *** were related to their population adaptation toward water temperature,depth,and prey-searching periods.
