Silt striders are giant, brown colored, flea-like creatures that produce a deep eerie call that echos across the land. The gigantic arthropods were domesticated by the Dunmer long ago and are used for transportation. The Dunmer cut away a portion of the hard outer shell to expose sensitive tissue beneath, which can be goaded with minimal force to guide them and to make room for passengers and cargo.
Silt striders are said to be tough enough to withstand the harshest of Morrowind's weather but the eruption of the red mountain has pushed them to the edge of extinction. After two hundred years an old silt strider on the verge of death named Dusty is one of the few remaining.
