FIGURE 1 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)

FIGURE 1. (A) General view of the holotype and the paratype (from left to right, respectively) of Spiculosiphon oceana sp. nov. (B) Detail of capitate region of the holotype, showing the globelike, central structure and the radiating tracts of spicules. (C) Globelike region of the holotype, showing the irregular, loose arrangement of spicules. (D–F) Views of stalks. One of the collected stalks (D) had a calcareous foraminifer (f) attached and also some flocculated debris (d). The stalk in E shows the tightly packed spicules to be slightly twisting with respect to the stalk axis. The stalk in F shows a region in which the translucent spicule wall gets a brownish to purplish coloration. (G) Detail of the proximal end of a stalk, showing that it is a closed structure, slightly expanded into a bulb-like form.
