Variation in the endogenous intact waxes of odontocetes: There is more than one way to build an acoustic receiver

Abstract

Odontocetes possess specialized fat bodies in and around the mandibles for sound reception which have complex topographical distributions of unique endogenous lipids (triacylglycerols and wax esters [WE]). Although there is diversity across species in the fatty acid (FA) and fatty alcohol (FAlc) components of
