The class of the mermaid's glove sponge is Demospongiae, which is the largest and most diverse class of sponges. They are characterized by having a skeleton made of spongin fibers or siliceous spicules.
Phylum Porifera Class Calcarea Order Calcinia Order Calcaronia Class Hexactinellida Order Amphidiscophora Order Hexasterophora Class Demospongiae Order Homoscleromorpha Order Tetractinomorpha Order Ceractinomorpha Phylum Porifera Class Calcarea Order Clathrinida Order Leucosoleniida Order Sycettida Order Leucettida Class Hexactinellida Class Demospongiae Order Haplosclerida Order Poecilosclerida Class Sclerospongiae
The largest class of sponges is Demospongiae, which includes over 90% of all known sponge species. Their body type is typically characterized by a leuconoid structure, which consists of a complex network of canals and chambers that allows for efficient water flow and filtration.
Phylum ahead of the class, order, family, genus and species. There are four classes; three of them are Calcarea, Hexactinellida and Demospongiae
Most sponges of the Demospongiae type are considered asymetrical. (Not having symmetry.)

The brown tube sponge is of Kingdom Animalia, phylum Porifera and Class Demospongiae. It is further classified as Order Agelasida, Genus Agelas and species A.conifera.
The three classes of sponge skeletons are siliceous or glass sponges (Class Hexactinellida), calcareous sponges (Class Calcarea), and sponges with a fibrous protein skeleton (Class Demospongiae). Each class has unique structural characteristics that support the sponge's body.
The Brown Bowl Sponge is Cribrochalina vasculum, in the class Demospongiae.
Tube Sponges are in the Class: Demospongiae, subordinate to the Phylum: Porifera.
The Demospongiae are the largest class in the phylum Porifera. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. They contain 90% of all species of sponges.
The giant barrel sponge is classified as Xestospongia muta. It belongs to the kingdom Animalia, phylum Porifera, class Demospongiae, order Haplosclerida, and family Petrosiidae.
