From the How to Train Your Dragon Wiki:
- "A Tidal Class expert in camouflage that buries itself in the sand. It's a good way to surprise their prey...and avoid sunburn!
- "Unlike other dragons, the Sand Wraith has a unique fire power. It shoots hardened balls of sand surrounded by weak fire from a distance. The Sand Wraith makes full use of its sandy habitat, the beaches and the deserts. It buries itself in sand for long periods of times, waiting for unsuspecting prey. Then, it ambushes it and strikes. It is an excellent, ingenious idea as it prevents potential prey from spotting it. The beach and desert is a rather hot environment and thus, this method also helps prevent the Sand Wraith from getting sunburn. The very fact that the Sand Wraith is able to come up with the ingenious idea of hiding in sand shows that the Sand Wraith is highly intelligent. It is able to solve problems and improvise on solutions. They are able to make good use of their environment. Their problem solving skills and critical thinking is similar to that of a human. These skills are useful when hunting."
