Sex ratios of the inarticulate brachiopod Glottidia pyramidata were investigated for a subtidal population in Tampa Bay. Of the specimens examined, 47.7% were male; 51.6% female and 0.7% hermaphroditic. Hermaphrodites were most common when population densities were lowest. The evolutionary significance of hermaphroditism is discussed.
