Marine diatom genus Skeletonema is widely distributed in coastal areas around the world. We showed that the four species to appear from gene analysis and morphological observation in Tokyo Bay(S. dohrnii, S. japonicum, S. tropicum, and S. j-d). For these species, the growth rate of various water temperature and salinity were measured. The highest growth rate was showed in S. dohrnii, and physiological charactaristics were liked to be euryhaline and eurythermy. S. japonicum was late growth than previous specie, and prefer a low temperature. These physiological characteristics were well reflected their distribution in Tokyo Bay.

海洋硅藻属骨条藻广泛分布于世界各地沿海地区。通过基因分析和形态观察，我们发现东京湾出现了四种S. dohrnii、S. japonicum、S. tropicum和S. j-d。对于这些物种，测量了不同水温和盐度的生长速率。其中S. dohrnii生长速度最快，生理特性为广盐性和广温性。日本血吸虫比以前的物种生长晚，喜低温。这些生理特征很好地反映了它们在东京湾的分布。
