Animals with only two germ layers: ectoderm and endoderm. They lack complex organs and a central nervous system.

Mesoglea

A non-cellular, jelly-like layer found between the ectoderm and endoderm in diploblastic animals.

Diffusion

Substances are moved around in the body of diploblastic animals by this process.

Neuron Net

A network of interconnected neurons, rather than a central nervous system, found in diploblastic animals.
