Morphological description (show/hide)
| Massive, globular or elongated-globular sponges of about 0.8 to 2.5 cm. One or several large oscular openings of about 1.5 to 3 mm. | | Yellow | | white | | One to several | | Smaller triactines, equiangular and equiradiate and tetractines, which lie woiht thir basal wall tangentially to canal walls, with their apicla actine protude into the canal. | | Large cortical triactines and smaller cortical triactines of size and shape of coanosomal triactines. | | Large cortical triactines: equiangular, equiradiate, with conical, sharp-tipped actines (actines: 279 - 373.9 - 481?m x 26 - 39.3 - 48 (n=5). Smaller cortical triactines of size and shape of choanosomal triactines, which are equiangular and equiradiate, with conical, sharp-tipped actines: 81 - 143.6 - 190 ?m x 9 - 15.2 - 22?m (n=23). Tetractines of canal walls: Equiangular and equiradiate, with conical, sharp-tipped actines, the basal system with slightly shorter actines than the smaller triactines: 92 - 116.9 - 143 ?m x 9 - 11.9 - 16?m (n=20). The apical actines are straight or slightly curved. |
