Many plants in the okapi’s diet contain defensive chemicals. Okapids produce large amounts of saliva to help neutralize these toxins. Saliva binds harmful compounds before digestion. This allows them to safely consume plants others avoid. It expands their available food supply. This adaptation reduces competition.
This shows how internal physiology can shape ecological roles. Diet determines survival.
The okapi’s feeding niche depends on chemical tolerance. It is a quiet but powerful advantage.
Okapids can eat plants that are lethal to other herbivores.
