P.d. lived on the riverbank very close to the river water. When the gates were opened to demolish the dam, P.d. horizontally moved over 30 m to acquire a new wet place depending on the reduction of the lake-water level. It was found that P.d. was an amphibious shellfish living both in fresh water and air.}, title = {ウスイロオカチグサは湿気を求めて旅をする?}, year = {2020}, yomi = {ニシノ, ヒロシ} }
