发光海洋介形虫Vargula hilgendotfii，也被称为“海萤”，的地理学表明，这种生物可能是在大约10，000年前的最后一次冰川时期相对较近地到达日本岛屿的。系统发育关系也强烈表明，日本海流驱使海萤介形虫向北移动。很明显，海萤介形虫迅速扩散到日本主要岛屿以北3,000公里处，而在日本岛屿西南部，它的扩散缓慢，覆盖了400公里的距离。日本海流在北纬28度经过托卡拉海峡时的弯曲可能是海萤介形虫扩张的障碍。
The biogeography of the luminous marine ostracod Vargula hilgendotfii, also called "Umihotaru," shows that this organism may have arrived relatively recently on the Japanese islands during the final glacier period approximately 10,000 years ago. Phylogenetic relationships also strongly indicate that the Japan Current drove the Umihotaru ostracod northward. It is evident that the Umihotaru ostracod spread rapidly to the major Japanese islands 3,000 km north, whereas its spread was slow in the southwest of the Japanese islands, covering a distance of 400 km. The meandering of the Japan Current, where it passes by the Tokara Gap at 28 degrees N latitude, may be a barrier to Umihotaru ostracod extension.
