Dravek

Dravek a non-sentient species native to the planet Turrawuste. Dravek are massive, worm-like creatures with large mouths ringed with teeth. They hunt their prey by burrowing under their planet's sand and then attacking from below, usually swallowing their prey as they come up from underground.

Ben and the Highbreed Reinrassic III were trapped on Turrawuste after a teleporter ring malfunctioned, and the two formed an uneasy alliance in order to get off the planet. The pair were attacked by a dravek, but managed to defeat it and sent it back down underground.
