N2 - 1. 1. The fatty acid composition of the total phospholipid fraction was determined for specimens of Paralvinella palmiformis from hydrothermal vents on the Juan de Fuca Ridge. 2. 2. Animals collected from 17°C water had a significantly greater degree of fatty acid unsaturation than animals living at ca 30-40°C. 3. 3. Compared with two shallow-water, non-vent polychaetes from the same family (Hobsonia florida and Amphicteis scaphobranchiata), Paralvinella has a greater proportion of 18:1, 18:2, and total polyunsaturated fatty acids and a smaller proportion of 20:1, 22:1 and total monounsaturated fatty acids.
