Calcifibrospongiidae
Calcifibrospongiidae is a family of Sponge, sponges belonging to the order Haplosclerida. The order Haplosclerida is distinguished by isodictyal skeleton (mesh shaped fibres). In general, Porifera are basal animals with bodies full of pores and channels. Calcifibrospongiidae includes the species ''Calcifibrospongia actinostromarioides''. 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. Description Calcifibrospongiidae are Demosponge, sclerosponges, with a basal skeleton made out of calcium carbonate, which encloses the sponge tissue. Scelorsponge skeletons are Polyphyly, polyphyletic, causing this family to be classified because of its Sponge spicule, spicule skeleton. Sclerosponges are Relict (biology), relict forms of sponges that originated from Paleozoic groups. They have derived from two possible sources; the first being from the desmosponges during the Paleozoic and in recent ages div ...
