Figure 1. A in Discovery of a new scale worm (Annelida: Polynoidae) with presumed deep-sea affinities from an anchialine cave in the Balearic Islands (western Mediterranean)

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.
