Abstract
    Specimens of the deep-sea benthic shrimp Nematocarcinus gracilis were collected from 900 m to 1000 m in the Arabian Sea, close to where the permanent oxygen minimum zone meets the sea floor. Lipid profiles, encompassing total lipid, lipid class and fatty acid composition, were compared with previously reported crustacean lipid assays and provided an insight into the life history of the species. The major storage lipid in N. gracilis was triglyceride, supporting the supposition that this species exists in benthic regions. Neutral lipid levels were commensurate with N. gracilis being an opportunistic feeder. Fatty acid composition was typical of an organism with a diet based on an ultimately photosynthetic source of organic carbon, but also reflected the reduction in the availability of labile organic carbon (in the case of lipid, highly unsaturated fatty acids) in the deep sea.
