Sandcrabs are insectoids encountered for the first time in the Ddiddiwedht Desert, which Geralt of Rivia and Avallac'h traverse in The Witcher 3: Wild Hunt. Sandcrabs are not particularly strong opponents. As it turns out, they are only dangerous in large quantities. An important fact is that sandcrabs can suddenly jump out of the ground in a similar fashion to giant centipedes.
Sandcrabs have well-developed carapaces, and two pairs of legs and a pair of wings, even though it is unknown whether the creatures are able to fly. A most eye-catching feature is the very long horn on their heads.
