In fact, their body is made up of about 90% water! What kind of mouth does the Aequorea victoria have? [10], This discovery led to great advancements in the field of medicine because it allows for further understanding in treatments and medical diagnoses through research in cells and bacteria.[11]. [6] Many larger specimens are found with the parasitic hyperiid amphipod Hyperia medusarum attached to the either the subumbrella or exumbrella; these amphipods may burrow into the jelly, but such activities are not lethal to the jellyfish. The aptly named crystal jelly is clear but may glow greenish-blue. Their bell-shaped body has an opening, which serves as a mouth and anus.

Because crabs live in the ocean depths, they often have difficulty accessing several jellyfish. Reproduction: Crystal jellyfish reproduce just like any other possible jellyfish as they can do so both sexually and asexually. These features are fairly plastic, and the numbers of tentacles and radial canals increase in all species of Aequorea with size. Jellyfish tentacles with stinging cells serve as a defense and a powerful weapon for catching prey. .
