Deserts & Xeric Shrublands
Southwestern Africa — Namibia and Angola
Description
The Namib is among the world's oldest deserts, receiving moisture primarily from coastal fog rather than rain. Fog-basking beetles, sand-diving lizards, and the endemic Welwitschia plant have evolved remarkable adaptations to extreme aridity. Detritus blown from the interior provides energy subsidies to fog-dependent dune communities.

Key Interactions
- Fog-basking beetles collect moisture by tilting their bodies into coastal fog
- Welwitschia plants survive for over 1,000 years using fog moisture and deep taproots
- Wind-blown detritus from the interior subsidizes dune invertebrate communities
- Brown hyenas patrol the Skeleton Coast scavenging seal carcasses and beached marine life
