It sounds like you might be thinking of a hybrid creature or a play on words!
Perhaps you're thinking of:
* "Sharknado" movies: These films are known for their ridiculous premise of sharks being sucked up by tornadoes and wreaking havoc.
* "The Meg": This film features a giant prehistoric shark known as Megalodon.
* "Jaws": This classic horror film features a great white shark terrorizing a small seaside town.
