Field observation of spawning ground of horseshoe crab Tachypleus tridentatus was carried out in August 2000 at a river mouth in Seikai-cho in Nagasaki Prefecture. Many eggs spawned under thegroundof river mouth bars were found. Morphological features of spawning ground including surrounding vegetations were investigated and compared with the results of the former studies. Results were well explained by the features summarized in the former studies. A note on conservation of rare species was discussed.
