Glass sponges
Hexactinellida, Calcarea, Demospongiae, andSclerospongiaeTechnically, 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.
Some species of sea sponges are threatened by factors like habitat destruction, pollution, and overharvesting. It is important to monitor and protect these organisms to ensure their survival in the oceans.
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 examples of asexual animals are flatworms, starfish, and certain species of insects like aphids. These animals are capable of reproducing without the need for a mate through processes such as fragmentation, budding, or parthenogenesis.
The collar cells of sponges are similar to choanocytes, which are specialized cells found in both sponges and some types of colonial protozoa. These cells have a collar-like structure with a flagellum that helps in creating water currents to bring in food particles for the sponge to consume.

Glass sponges are considered the class Hexactinellida.
Its made up a fiber that resembles fiberglass.
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).
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.
In calcarea spicules are calcareous, in hexactinellida spicules are silicious and hexa radiated, in demospongiae spicules are absent but spongin fibres are present. that's why demosponges are used as bathroom sponges
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.
There are thousands of different types of sponges, so there's not enough room to list them all. Here's a great website showing several hundred different sponges found in the Caribbean so you can get some idea of the different groups they fall into.
Phylum Porifera or Sponges are the invertebrates are simple animals,live in water,cannot move from one place to another and have foul smell. Examples are: Sponges Sycon Spongilla Euplectelea .
Worms, Mollusks and sponges are examples of invertebrates.

invertebrates are animals which do not have a skeleton made up of bones . Some examples of invertebrates are - Jellyfish , Corals , Starfish , Sponges , Crabs and Shrimps
