- Order: Piscine Wyvern
- Suborder: Fish Feet Wyvern
- Superfamily: Water Wyvern
- Family: Plesioth
Much like their relatives, the Green Plesioth are top predators, especially in water. They often catch and eat Aptonoth, Epioth, Sharqs, sea birds, frogs, and crocodiles. In the New World, these creatures must live alongside other large aquatic predators all of which are Leviathans in the Flooded Forest and Deserted Island. Lagiacrus and Gobul are major threats to Green Plesioth.
Green Plesioth has many of the same adaptations of PLesioth, however, there is a few differences between the two. The biggest differnce between the two is their hunting style. Both of them are said to have the opposite hunting style. While Plesioth prefer to hunt in the water, Green Plesioth prefer to hunt on land.
Green Plesioth is a highly aggressive wyvern, normally attacking hunters.
