Whip

Whips are a non-sapient species of giant predators from the mist-covered jungles of Venus.

Biology
Whips are 50 ft tall (15.24 meters) reptilian bipeds with short clawed forelegs, a lupine narrow snout, fangs and large ears. They are named for their prehensile, razor-edged, whip-like tongue, which is as long as the creature's entire body, and can be used to wound and to grab Human-sized prey with ease. Whips emit shrieking vocalizations.
