The order Haplosclerida is distinguished by isodictyal skeleton (mesh shaped fibres).

There have only been ten recorded occurrences of this species: in Hogsty Reef and San Salvador, as well as in the subtropics of the Bahamas.

Calcifibrospongiidae are sclerosponges, with a basal skeleton made out of calcium carbonate, which encloses the sponge tissue.

[5] It is covered in oscules which are regularly scattered to provide a means for water to pass through.

[1] The siliceous strongyles are held together by spongin fibres and the calcareous skeleton sits around this structure.

To date, the shallowest specimen found was collected on a reef at Acklins island in the Bahamas at a depth of 30 m (98 ft) by W.M.
