Fig. 6.6 Spawn, stomach contents, fecal pellet and radula of Recent Triphoroidea (from Nützel
1998). (a–d): Egg chamber of Cerithiopsis sp. in the sponge Suberites domunculus, Recent,
Mediterranean (a, b). Same view, surface of sponge showing sealed opening (dashed line) with an
cerithiopsid embryonic shell emerging from the chamber (arrow). (c, d). Egg chamber in transverse section with several cerithiopsid embryonic shells. (e, f) Sponge spicules from a stomach of
a cerithiopsid. (g) Shrinked fecal pellet of a triphorid containing sponge spicules. (h) Rhinioglossate
radula of a Triphorinae species, R rachidian, L lateral, M1–M6 marginal teeth. Scale bars (a–d):
0.3 mm, (e): 50μm, (f): 3μm, (g): 30μm, (h): 10μm
