Okapids live in extremely wet rainforest environments. Their fur is coated with natural oils that repel water. This keeps their skin dry even during heavy rainfall. The oily coat also helps prevent fungal growth. Water slides off instead of soaking in. This adaptation keeps body temperature stable.
This matters because constant dampness can cause illness. Staying dry reduces energy loss and infection risk.
It shows how even fur chemistry evolves for survival. Small details make a big difference.
