Figure 5. (A), Morphotraits of Heterorotula kakahuensis (as Ephydatia kakahuensis, New Zealand) vs Ephydatia fluviatilis (eastern Europe, original plate after Traxler 1896). E. kakahuensis 1–2, gemmule and detail of foramen, 5–8, long birotules as gemmuloscleres, 9–11, spiny oxeas as megascleres. E. fluviatilis 3–4, gemmule and detail of foramen, 12–14, short birotules as gemmuloscleres. Not to scale. (B) Ephydatia kakahuensis (modified after Schröder 1935). (Ba) megascleres. (Bb) gemmuloscleres (lateral view). (Bc) gemmuloscleres (top view); the gemmuloscleres are very similar to those of several other species of Ephydatia. Not to scale.Published as part of Pronzato, Roberto & Manconi, Renata, 2019, Journal of Natural History 53 (35) on pages 2207-2229, DOI: 10.1080/00222933.2019.1694716, http://zenodo.org/record/365489
