Okapids possess scent glands on their feet that release a tar-like substance. As they walk, they leave behind a chemical trail on the forest floor. Other okapids can detect these trails to navigate territories. This system allows communication without visual contact. In dense rainforest, scent is more reliable than sight. Trails can last for hours or days depending on conditions.
It demonstrates an advanced form of non-verbal communication. Chemical signaling reduces unnecessary encounters and conflict.
This behavior shows how animals adapt communication methods to their environment. It also underscores the complexity of rainforest ecosystems.
Okapids can recognize the scent of specific individuals.
