To catch Mosasaur you have to use a special trap
The Mosasaur is not a kind fish, but a true sea monster, the Mosasaur uses its powerful fins to propel itself, with open jaws, towards its enemies. Somehow the Mosasaurs have managed to reach the Invizimal world, which confirms the connection between dinosaurs and Invizimals.
