| Demospongiae | Dendroceratida | Darwinellidae | Chelonaplysilla "erecta" | 1 | Soft, dark purple cushions-encrustations. Skin looks paler than oscular collars. In the W. Atlantic this species has been named C. erecta (Row, 1911), which is a name for the Red Sea. It probably needs a new name. | (Row, 1911) | purple-violet,encrusting,soft |
