Brief SummaryRead full entry
Syringammina corbicula is a species of xenophyophore (Foraminifera) that was discovered living at 3106-meter water depths on the Cape Verde Plateau, off West Africa (Pawlowski et al. 2003, Richardson 2001). This species possesses a hemispherical test comprised of anastomosing agglutinated tubes. Unique basket-like depressions rim the periphery of the test. Like other xenophyophores, S. corbicula possesses: granellae (intracellular barite crystals), granellare (cytoplasm enveloped by a thin organic wall), and stercomata (stercomes enclosed within a membranous casing). Like other foraminiferans, S. corbicula possesses granuloreticulose pseudopodia that it extrudes through openings in the test wall. Syringammina corbicula occupies an epibenthic habitat and captures suspended food particles in the web of pseudopodia that stretches between the branches of its tubular test.
