But if you think that's all you've got to worry about, check your setting: if you're somewhere other than Earth, be it a sci-fi or fantasy world, then tread softly; without rhythm and check the ground often, because you may just wind up with a case of Sand Worms.
You've got dehydration to worry about, of course, then there's heatstroke, scorpions, snakes, pack animals of dubious trustworthiness, and native peoples who may be ruthlessly territorial or just poorly disposed toward your particular ethnicity.
Intelligence varies but is usually pretty animalistic.
They may be loners or travel in packs, again depending on how threatening the writers want them. Even in the best of cases, these are obvious instances of artistic license; it simply isn't possible for a creature so dense and large to pass that easily through heavy earth, even if it is fine sand.
Beyond these basic traits, even the most incidental similarity to real creatures ceases.

Aside from the worm-like shape, these monsters are also recognizable by their mouths: they're always either completely round or trifurcated, lined with rows of teeth, and with long tentacular tongues, the better to grab you by the feet and reel you in.
“People hold a stereotype of the liar—as tormented, anxious, and conscience-stricken,” De Paulo and Bond write.
(The idea that a liar’s anxiety will inevitably become manifest can be found as far back as the ancient Greeks, Demosthenes in particular.) In fact, many liars experience what deception researchers call “duping delight.”Aldert Vrij, a psychologist at the University of Portsmouth, in England, argues that there is no such thing as “typical” deceptive behavior—“nothing as obvious as Pinocchio’s growing nose.” When people tell complicated lies, they frequently pause longer and more often, and speak more slowly; but if the lie is simple, or highly polished, they tend to do the opposite.
