| Research Abstract |
Sulfur isotope ratio(∂^<34> S) of statolith of Aurelia sp. was analyzed. The∂^<34> S of statolith of Aurelia sp. medusae which were raised in seawater of 10.8‰(sd=0.26, N=10) was 12.0‰(sd=0.20, N=3), those in seawater of-0.4‰(sd=0.21, N=7) was 2.2‰(sd=0.07, N=2). The isotope fluctuation was+0.7～+2.2‰.
