Here's my concept for the most prominent tapeworm species in Jelliena:
1. Jellicrompom serpentidae or the snake tapeworm is a very common tapeworm species, living comfortably inside or outside of their hosts which can be any species but they're more common for birds, small mammals, reptiles and amphibians.
2. Tellbellum Angulis or the eel tapeworm is a marine tapeworm that hunts like a moray eel. It coexists with the larger Tiburolithes Mangillica or the shark tapeworm. The shark tapeworm hunts like a great white shark. Where the eel tapeworm hunts fish, the shark tapeworm hunts seals, fish, seabirds, otters, dolphins and the occasional young whale, Pliosaur, Plesiosaur, Mosasaur, or Ichthyosaur.
