Vosmaer, 1886
Definition: Thin growth form, soft texture and gelatinous surface characterise this family. The fibrous skeleton is absent entirely. Choanocyte chambers consist of specialised wide-mouthed, extended tubular and branched eurypylous forms. Parenchymella larvae are simple, lacking long terminal cilia.
Remarks: The group is of doubtful affinity and inclusion in the Dendroceratida is convenient only; recently a proposal for a new order Halisarcida has been made which still needs general acceptance. Only a single genus is recognized. Review: Bergquist, 1996.
