Fossil sea sponge.

Structure and Function in Sponges. Sponges are diploblasts meaning that they develop from two basic germ layers: an ectoderm, or outer layer, and an endoderm, or inner layer. Most sponges are asymmetric. Asymmetry means that if the animal is divided into two halves along any axis, the halves will not be equal or identical.
