Characteristics of Sponges?

Answer

One of the characteristics of sponges is that although they are a marine animal, they reproduce in a manner similar to plant. Mesohyl, which is mostly collagen, fills the area between layers of cells to provide skeletal structure. They do not have muscles, true tissues, circulatory or nervous systems, nor do they feel pain. Sponges are able to adapt to many diverse conditions, with some able to live in fresh water. They have pores which intake fluid and food, filtering them as they pass through.
