The members that live exclusively at great depth ("benthic") show remarkable adaptation in the lipids that constitute their cell membranes — in hindsight, perhaps not surprising, given the sensitivity of membranes to changes in pressure. SImulations, fluorescence spectroscopy, and high pressure small-angle x-ray scattering suggest that the benthic animals have adapted their lipidomes to retain access to highly curved membrane phases at high pressure. This is achieved by a spectacularly modest change in lipid chemistry, highlighting how tiny changes in chemistry can produce drastic changes in continuum properties of membranes.
