Figure 1. A, map of the Balearic Islands showing the known localities (red numbers) of the new cave polynoid worm Pollentia perezi gen. & sp. nov. (1), the stygobiont cirolanid isopod Metacirolana ponsi (1 and 2) and the stygobiont mysid Burrimysis palmeri (1, 2 and 3); these three taxa occur only in full-strength marine water layers of anchialine caves. B, plan view and section of the cave harbouring the new polynoid (after Suárez, 1993; modified). C, temperature and salinity profiles of the anchialine lake harbouring the new polynoid (notice euhaline conditions below 11 m depth). Temperature, salinity and depth profiles were obtained with an RBR XR-420 conductivity, temperature and depth (CTD) profiler.
