Jellyfish are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblastic which have three main layers. The two main cell layers of jellyfish are the exoderm on the outside and the gastroderm on the inside, in the middle is the mesoglea which functions as a skeleton.
