The main components of their bodies are syncytia in which large numbers of cell share a single external membrane. Calcarea have skeletons made of calcite, a form of calcium carbonate, which may form separate spicules or large masses.

Answer:
The internal skeleton of a sponge is made up of structure called Spicules.
Explanation:
Spicules are frequently sorted by size, the bigger being megascleres and the littler microscleres. It's further classified as natural and chemical based upon its composition. Spicules made up of chemical substances such as calcium carbonate and silica is chemical ones, while others which are made of a spongin are called as natural one.
This chemical composition of the sponges gives the organism a spongy like appearance and thus facilitates the organisms function.
