Extracellularly in a digestive cavity.
Cnidarians have a mouth/anus, tentacles, stomach cavity, and skin.

Phylum Cnidaria, which includes jellyfish and corals, does not have a circulatory system. Instead, they rely on diffusion to transport nutrients and gases throughout their body. This is possible due to their simple body structure and the presence of gastrovascular cavities.
