Such animals do not live now, but did once.

Hydrotherosaurus and Quetzalcoatlus are the names now given to species of dinosaur that lived late Cretaceous geological period.

Hydrotherosaurus was a plesiosaur reaching up to 13 meters in length.

Quetzalcoatlus was a pterosaur (a type of flying dinosaur) with a 10-11 meter wingspan.
