Comment:

Substrate: live Stephanocoenia michelini; Sampled and identified by K. Rützler. All measurements are of mature, fully formed oxeas to allow statistical comparison with other samples. Measurements conducted C. Schönberg on preparation of acid-cleaned spicules made by C. Schönberg. Data are sorted vertically by spicule width.; Rützler, Klaus (1971) Bredin-Archbold-Smithsonian Biological Survey of Dominica: burrowing sponges, genus Siphonodictyon Bergquist, from the Caribbean. Smisthonian Contributions to Zoology 77: 1-37 (USNM 24094: pp. 5-10, Fig. 10, Tab. 2, Pl. 3-6 and 8-9).
