Hexactinellida, Calcarea, Demospongiae, andSclerospongiae
Technically, however, the Sclerospongiae are not considered sponges. They are very similar, but they are not the same. Like bats and birds who have both evolved the ability to fly but are not the same types of animals, Slerospongiae have evolved and became very similar to sponges, but they are not sponges.
Calcarea, Hexactinellida, Demospongiae, and Sclerospongiae are the four classes of sponges. The class a sponge is in is determined by the type of spicules.

Glass sponges
As far as officials know, most sponges are not endangered. Very few aquatic sponges are harvested and this small number is not large enough to have an effect on their population. There are over 5000 varieties of known sponges and only some fresh water sponges are known to be in danger at this time.
Some are, but there are so many.
Some names of asexual are worms,sponges,and much more
Modern sponges are predominantly marine, with some species adapted to freshwater environments, ranging from the inter-tidal zone to depths of 6,000 meters (19,680 feet). Certain types of sponges are limited in the range of depths at which they are found. sponges are worldwide in their distribution, and range from waters of the polar regions to the tropical regions. sponges are most abundant in both numbers of individuals and species in warmer waters.www.junglewalk.com/photos/Sponge-pictures.html
porifera are also called sponges some of the sponges are euplectelia spongilla and sycon
Glass sponges
There is no such nomenclature. Mollusks and sponges are two forms of invertebrates.Some sponges, such as Myxilla incrustans form symbiotic relationships with some mollusks (i.e scallops).
Most sponges are marine, but there are some freshwater varieties
sponges are use in washing plates,glass of water.some sponges are in/on salted water on the ocean floor.
The Porifera are the sea sponges. Some simple examples are the kitchen or bath sponges or other sponges that one can see diving -- from barrel to branch sponges.
Some sponges protect themselves and they don't even know it. Those sponges protect themselves by a hard outer layer of skin.
The first sponges were natural. They are some of the oldest animals to ever live on earth.
Some things that prey on sponges are sea turtles, crustaceans, fish, and echinoderms. Sponges move so slow that they cannot avoid being eaten.

Sea sponges do not have many natural predators. The only animal that has been known to feed on sea sponges are sea slugs.
Sponges live in saltwater lakes, sea, and oceans. Some sponges live in freshwater.
