Two species of teleosts, Hoplostethus gilchristi and Rexea solandri, caught off New Zealand have been found to possess wax esters or diacyl glyceryl ethers in the muscle as a major lipid. The muscle of H. gilchristi contained 7.9% lipids, in which wax esters made up 97%. The component fatty alcohols were mostly saturated or monoenoic and contained 14-24 carbon atoms. The major constituents were cetyl alcohol, eicosenol, and docosenol: each occupied 21-24% of the alcohol total. Oleic acid was dominant among the fatty acids of the wax esters. The muscle of R. solandri contained 18.6% lipids, of which 30% were diacyl glyceryl ethers and 68% were triglycerides. The major glyceryl ether components were selachyl and chimyl alcohols, which constituted 60% and 23% of the glyceryl ethers respectively without polyenoic alcohols. The fatty acid compositions of diacyl glyceryl ethers were similar to those of triglycerides; palmitic and oleic acids were the chief components.
