Leptocleidus sciifii (name meaning "SciiFii's Leptocleidus") is a species of medium-sized pliosaurid plesiosaur that originally lived in what is now British Isles during the Early Cretaceous and was once extinct, but Leptocleidus sciifii has since been brought back from extinction by SciiFii and now lives in Cretaceous Park located in Sacramento, California. Unlike most other species of plesiosaurs, it is a freshwater animal instead of a saltwater animal, it is also about the size of a medium-sized dolphin, allowing it to fit through many of the rivers. It is a carnivore that mainly feeds on a wide range of freshwater fish and crustaceans, but in Cretaceous Park, it is given koi, goldfish, and common food shrimp, rather than salmon or other modern wild fish or crustaceans, to reduce the risk of endangering the native modern wild fish or crustacean species. It is a solitary animal that lives most of its life alone, but can congregate with other Leptocleidus sciifii during breeding seasons.
