Swimming Sharpteeth are a type of Sharpteeth that live in the water. They're first appearance can be dated to the original movie during the opening scene, even before the term was official in later sequels such as the 5th and 9th films. Most are unable to go onto land, though some, such as Nothosaurus, have been seen on land. They are also dubbed Sharptooth Swimmers, particularly pliosaurs.
- Frank Welker (IV, V, IX)
It's unknown if friendly Swimmers like Elsie and Mo would be considered Swimming Sharpteeth because they do not attack dinosaurs, though they are carnivores (though they lack sharp teeth unlike their reality counterparts). They have only been called Swimmers (though some speculate that plesiosaurs would be called "Swimming Longnecks").
