Silt Striders are giant arthropods, which can be up to 60 feet tall. Used as a means of transport in Vvardenfell by manipulating exposed organs and tissues. Silt Striders are a resilient species whose tough carapace helps them survive the adverse environment of the island. Silt Striders survived the Ash Blight that exterminated many of Vvardenfell's native creatures, such as the Cliff Strider. Their numbers would however dwindle due to the coming of the Red Year, when the eruption of the Red Mountain killed most of them and destroyed their native habitat.
Smallers anthropods named Silt Hoppers are used by Ashlanders. It is unknown if they are young Silt Striders or different creatures. Large limbs can be atached to ships for deep sea fishing, smaller legs can be used for fishing rods.
