Do Jellyfish Have Testicles. The body of an adult jellyfish consists of a bell shaped hood enclosing its internal structure and from which tentacles are suspended. With their gelatinous bodies, strandlike tentacles and other strange features, jellyfish appear to be very different from other types. They also have two sticky tentacles that help them capture prey. There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs directly into the water. In the adult, or medusa, stage of a jellyfish, they can reproduce sexually. Jellyfish, because of their planktonic lifestyle, are predatory animals. Throughout their lifecycle, jellyfish take on two different body forms: Sometimes, these flatworms turn directly into adult jellyfish, but some settle onto rocks and undergo another. Jellyfish reproduction involves several different stages. Under favourable conditions they will do this once a day, usually synchronised to dawn or dusk. In their tentacles we find nematocysts, which are cells that have an internal capsule (cnidocisto) filled with stinging liquid and a filament.
