These towers are made by the male Red Sea Ghost Crab (Ocypode saratan). The crabs are found on the coast throughout Socotra, but they are only able to make these castles where the tides do not regularly reach.
Here in Erissel they dig deep to reach the wet sands, and thus these towers reach pretty high compared to their size. The sea reaches here only during cyclones or low pressures combined with spring tide.
