DIGESTIONS:
Immortal Jellyfish are carnivores, which mean they feed on other animals. They drift through the ocean current and trap food as they pass with their tentacles. Their food sources are zooplanktons, eggs, larvae, and crustaceans. Immortal Jellyfish likes most jellyfish have an incomplete digestive tract. The food go in through the internal cavity and the food also leave the jellyfish through the internal cavity. When food enters the internal cavity then it will enters the celetero, where enzymes break down the food and absorbs the nutrients.
Internal transport & Respiration:
Immortal Jellyfish are likes most of the jellyfish they have a very simple internal transport system. Since they have a thin and transparent skin, this allowed them to do a unique function that us, human's can't, and that function is called diffusion. They can breath through their skin and they can also use diffusion to help transport nutrients through their body.
