Lipid compounds in secretions of fishing bat,Noctilio leporinus (Chiroptera: Noctilionidae).
The distinctive odor ofNoctilio leporinus arises from oily secretions found beneath the wings in the subaxillary region. Analysis of secretions by gas chromatography-mass spectrometry identified 372 lipid compounds. Differences in number and chemical composition of glycolipids suggest that secretions of males from the same roost are more similar to each other than to other males or females. Differences in number and chemical composition of nonpolar lipids indicate that secretions of males are more similar to each other than to females. Since secretions differ between sexes, information on sexual identity and reproductive condition may be communicated. Individually unique lipid compositions further suggest that bats may be recognizable by their odor within the roost and while flying.
