Tubeworms were either `fed' sulfide for a period of 48 h prior to the experiment, or were `starved' of sulfide for a period of at least 96 h prior to the experiment.
Values are means ± s.e.m. (N values are given in parentheses). Different superscript letters after a value indicate a significant difference, using the Bonferroni corrected significance level of 0.0025.
