Sponges are extremely varied in shape, and they also have the ability to recombine cells after they are separated.
Sponges thrive in salty waters and fresh waters. They can live in both cold and warm conditions.
An example of this is the calcareous sponge.

Sponges may seem solid, but they have tiny holes, tunnels, and chambers.
2. Because sponges only consist of sponge cells, sponge cells have many jobs that are usually split up amongst different organs in other animals.
3. Sponges get their food through filter feeding. Filter feeding is when the animal sucks in water and filters out the food.
