While jellyfish and comb jellies have several anatomical differences, the basics are the same. Both have two major cell layers: the external epidermis and the internal gastrodermis. (Ctenophores also have musculature in their in-between layer, the mesoderm, but it likely evolved separately from the mesoderm found in bilaterians like people.)
