FIGURE 3 in New sponge species from hydrothermal vent and cold seep sites off New Zealand

FIGURE 3. Haliclona (Soestella) battershilli sp. nov.: A. Finely branched, tangled masses dominate sediment-covered hard substrate at the Southern vent field of the Calypso hydrothermal vent field (NIWA Stn KAH1004/8: image 1112; 37.688° S, 177.123° E, 190 m); B. Preserved holotype NIWA 32128, showing fragments of branches and large, flush oscules; C. Composite image of a histological section of paratype NIWA 52895, showing a cavernous choanosome through which occasional primary lines emerge towards the surface (red arrows), connected in places by unispicular secondary lines (white arrows), and the dense interstitial oxeas. Image in 3A captured by NIWA's DTIS (Deep Towed Imaging System) deployed from RV Kaharoa.
