Abstract
The body tissues of the colonial ascidian Eudistoma ritteri are shown by quantitative spectrographic analysis to contain up to the following amounts of related metals (parts per million of dry weight): titanium, 1512; vanadium, 471; and chromium, 144. Body tissues and tunic fluid show a pH of 1.5 due to the presence of sulfuric acid.Keywords
