Abstract Codakia orbicularis may obtain nutrients from chemoautolithotrophic bacteria. The chemical composition of the C. orbicularis was investigated because of this unusual source of nutrition, and because it is a human food source in the Caribbean. The lipid fraction of these molluscs is discussed in detail. Polyunsaturated fatty acids account for only 11–15% of the total fatty acids, and non‐methylene interrupted dienes are present as high as 9.5%. Cholesterol represents about 45% of the total sterols present.
