What is Demospongia?
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.
What function might spicules provide?
The major function of spicule is to provide structural support to the organisms. Spicules also play other roles and one of the roles is to provide deterrence from predators that might attack.
What types of spicules give a sponges body support?
Spicules are tiny structures of hard crystal that give the sponge it's shape. There are many different types of spicules, some examples are; acanthostyles, stongyles, and anatriaenes.
How many prongs do spicules of grantia have?

Why would spongin and spicules discourage predators from eating sponges?
spongin and spicules are the sponges body support and defence
How spongin and spicules discourage predator from eating sponges?
Spongin and spicules are the sponges body support and defence. They both cover a sponge, and if a predator eats it it will be hurt. It will be hard to eat it, because of the sharpness and roughness of the outside. Well at least in the spicules case.

Do spongin are made of silica spicules?
According to the online Merriam-Webster dictionary, spongin is a "scleroprotein that is the chief constituent of flexible fibers in sponge skeletons"
Infer how spongin and spicules discourage predators from eating sponges?
They get scared ofrece predators
What type of sponge material supports a sponges body structure?
A network of spongin or spicules.
What is the main difference between the classes Hexactinellida Calcarea and Demospongiae?
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
What 2 materials may compose a sponge skeleton?
1. spicules (calcium carbonate or silica) 2. spongin (protein)
What protein makes up a sponge?
The flexible protein fibers that make up a sponge are called spongin. The hard, tiny spikes found in sponges are called spicules, and they are made of silica or calcium carbonate.

Why are bath sponges soft?
The harder silica or calcium spicules are absent and the softer spongin remains.Answer:They are soft because they should not hurt the body parts while having a bath. the skin is too soft to use a bath sponge, if the sponge is too hard.
What sponges have a skeleton?
Sponges don't have skeletons! They are invertebrates which means the creature doesn't have a backbone, but in this case, it doesn't have a skeleton! (I think this is right, I apologize if it isn't)
