They act as intermediate hosts of endoparasitic helminths, with the infection being transferred to the definitive host fish after predation. Jellyfish is one company connected across the world by hundreds of brilliantly different people. , Jellyfish are armed with nematocysts.  The mouth opens into the gastrovascular cavity, where digestion takes place and nutrients are absorbed.
