What special problems might an animal face if it lives under sand or mud?

It is possible for the animal to be trapped under the mud or sand.This can lead to suffocation or un-ability to get out which can starve or dehydrate the individual. You’re Welcome :)

My pigs teeth have already came in years ago, with my first molars, and my second molars are pretty much in. my wisdom teeth will be unable to come in, but i'm getting those out on monday.
