For the moment, it seems prudent to say that three distinct living types of animals may be called sponges and that at a basic level they may be easily distinguished by the type of skeleton they possess (Ruppert et al, 2003). In addition to variations in skeletal composition, numerous other characteristics also separate these groups. Those characteristics' differences often are obscure and require microscopic examination, so it seems easiest for this discussion to define the types of sponges by their skeletons.
