摘要

摘要/ Abstract摘要:2021年3月30日在冲绳岛沿海水域采集到stokesii水蚤。这是该物种在日本水域的首次记录，将其已知的活动范围向东北偏东扩展了900多公里。这条蛇是一条成年雌蛇，口长1,545毫米，尾长203毫米，体重3,360克。它的卵巢有11个发育良好的卵泡，胃里有一条半消化的多刺河豚(didon sp.)。这一个体可能代表了冲绳水域一个稳定的斯托克氏蜱种群。

Addition of the Sea Snake, Hydrophis stokesii (Reptilia: Squamata: Elapidae), to the Herpetofauna of Japan

Abstract: Hydrophis stokesii was collected in the coastal water of Okinawajima Island on 30 March 2021. This is the first record of the species from Japanese waters, extending its known range of occurrence toward east-northeast by more than 900 km. The snake was an adult female, 1,545 mm in snout-vent length, 203 mm in tail length, and 3,360 g in body mass. It had 11 well-developed yolked follicles in ovaries and a half-digested spiny puffer fish (Diodon sp.) in its stomach. This individual may possibly represent a stable population of H. stokesii in the Okinawan waters.
