FIGURE 4 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)
FIGURE 4. Results of EDS microanalysis at (A) the external side of the spicule wall of a stalk of Spiculosiphon oceana, (B) the wall of the stalk at areas bearing debris, and (C) the calcareous test of an unidentified, non-agglutinated, calcareous foraminifer attached to the stalk of S. oceana (see also figs. 1D; 3C).
FIGURE 6 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)
FIGURE 6. (A) View of the carnivorous sponge Asbestopluma hypogea soon after trapping a small copepod. The sponge is displaying the spiny-headed morphology, which is typical after a period of starvation in order to maximize the chances of new prey capture (Vacelet & Duport 2004). (B) View of the capitate region of the holotype and the paratype of Spiculosiphon oceana sp. nov. for a comparison with the body shape of the carnivorous sponge.
FIGURE 5 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)
FIGURE 5. Views of Spiculosiphon sp. specimens collected from 3PP cave some 18 years ago. (A) View of whole preserved specimen, with spicule tracts projecting from the spheroid being broken and artificially coalescing. (B) Schematic drawing of a live specimen. (C) Detail of the spheroid portion of the test showing damaged and coalescing, radiating spicule tracts (D–E). Details of the test of the stalk with densely packed spicules and some attached sand grains.
FIGURE 3 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)
FIGURE 3. SEM micrograph of stalks. (A) Tightly packed needle-like spicule fragments, with no obvious cement between them. Some debris (d) has flocculated on the spicules. Note that the silica of some of the oldest spicules started dissolving, as indicated by the occurrence of tiny cavities and pits (p) at their surface. Dissolution cavities are to be distinguished from accidental breakages (b) caused to the stalk during collection or laboratory manipulation. (B) View of the distal end of the stalk, showing that it is a closed, bulb-like structure. (C) Detail of a calcareous foraminifer (f) externally attached to the wall of one of the collected stalks (see fig. 1D). Note that a triaene (t) has been incorporated into the test and that some debris (d) has flocculated on the stalk.
FIGURE 2 in A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)
FIGURE 2. (A–C) Compound microscope micrographs showing the irregular arrangement of the spicules at the surface of the central globelike region of the test. Note the presence of needle-like spicule fragments along with three-rayed and four-rayed spicules (triaenes= t). (D–G) Views of the radiating tracts built by overlapping 2 to 3 spicules, which are held together by a translucent cement (c).
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.
FIGURE 1 in Flexammina islandica gen. nov. sp. nov. and some new phylotypes of monothalamous foraminifera from the coast of Iceland
FIGURE 1. Phylogenetic tree of monothalamous foraminifera based on 3' partial SSU rDNA sequences from our database and some GenBank sequences derived from environmental clone libraries (marked by the 'ENV' prefix and highlighted in bold). New sequences obtained in this study are marked by frames with the names of corresponding phylotypes / species given in bold; the name of every new sequence consists of two parts separated by dashes (foraminiferal DNA collection number and clone number). Foraminiferal DNA collection numbers and GenBank accession numbers (if available) are also shown for other sequences. Major monothalamid clades are indicated in accordance with Pawlowski et al. (2002, 2011).
