The giant false sawfish (Onchopristis sciifii) is a species of giant sclerorhynchid (sawfish-like chondrichthyan fish) that originally lived from the Lower Cretaceous to Upper Cretaceous of North America, North Africa, Brazil, as well as New Zealand, as an extinct species of Onchopristis, and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern lakes and rivers across North America, South America, and Africa to help boost biodiversity. It has an elongated snout that is lined laterally with barbed teeth to rake through the riverbed to find and then eat prey. The rostrum, or snout, is usually around 1–2 metres (3.3–6.6 feet) long. This sclerorynchid can usually grow to be about 5–6 metres (16.4–19.7 feet) long when fully grown. As with sawfish, its eyes are on top of its head to spot predators rather than prey, and its mouth and gills are under its body. The rostrum has electroreceptors to detect food in the water below them like most sharks and some rays. Unlike true sawfishes, the giant false sawfish doesn't tolerate saltwater and instead lives in freshwater habitats (lakes, rivers, etc) through its entire life, laying hard ray-like eggs in the riverbeds for safety against most predators. The giant false sawfish has almost no natural predators, except a few predators such as the African tiamat and the South American tiamat. The conservation status of the giant false sawfish is Least Concern, despite its size, due to successful conservation efforts, the giant false sawfish's wide range, and its tolerance to most of human activities.
