Integrative taxonomy of calcareous sponges (Porifera: Calcarea) from Réunion Island, Indian Ocean Author Klautau, Michelle Author Lopes, Matheus Vieira Author Tavares, Gabriela Author Pérez, Thierry text Zoological Journal of the Linnean Society 2022 2021-05-06 194 671 725 journal article 20247 10.1093/zoolinnean/zlab014 5cbb504f-e207-44fa-ac62-807a6de2f2db 0024-4082 6354284 3E370CBF-7DD1-4E73-BC37-81BF12EDFEED

Table 2. Spicule measurements of Janusya indica. H = holotype, P = paratype

Specimen	Spicule	Actine	Length (µm)				Width (µm)				N
* Hôzawa (1940) also gave, for the cortical triactines, the following measurements: 260.0 µm length/ 20 µm width. We consider that this measurement belongs to the large choanosomal triactines.
