Sand Ripper

Sand Rippers are sand-dwelling predators that reside in the Khoros desert that can "swim" through the sand and jump outside it for hunting.

Appearance
They are bulky olive green creatures with a distinctive row of spines reaching from their heads to the bases of their necks. There is a single large spine on the tops of the heads and an even larger one on their backs, somewhat like a dorsal fin. They have wide, gill-like markings along the bottoms of their necks, as well as narrow red eyes and prominent teeth that are visible even when their mouths are closed.

Powers and Abilities
Sand Rippers can swim through the sands and have protective membranes to shield their eyes so that they can "see" in the sand. They also detect loud movements above them and can launch themselves out of the sand to ambush their prey. They have jaws powerful enough to break the toughest metals, such as the Proto-TRUK's wing, and Kevin's Car.

Weaknesses
They are weak against large enemies and they can't walk on rocks.

Trivia

 * They are based on sand sharks and mosasaurs, which are prehistoric marine reptiles.
 * They also share traits with the Graboids from the Tremors film series. Both hunt underground, detect loud movements, and ambush prey.
