Research Abstract

It has been suggested that the invertebrates which inhabit at hydrothermal vents and cold seeps detoxify the hydrogen sulfide by accumulating taurine and its related compounds in their cells. In this study, we attempted quantification of taurine transporter(TAUT) mRNA to resolve whether this mechanism for detoxification of hydrogen sulfide universally exist among shallow-water and deep-sea invertebrates. On the basis of the result of sulfide exposure experiment, both deep-and shallow-water mussel showed the possibility of using the same mechanism for detoxification of hydrogen sulfide.
