5. The Compass Mounds of Western Australia
The termite mounds of Western Australia, particularly those built by Amitermes meridionalis, demonstrate remarkable architectural adaptation to environmental conditions. Known as "compass mounds," these structures are uniquely oriented north-south to regulate colony temperature. Rising up to 3.5 meters tall, these wedge-shaped mounds have a narrower east-west axis and a broader north-south axis. This design minimizes exposure to the intense midday sun while maximizing heat absorption during cooler periods, showcasing the termites' ability to tailor their constructions to local climate conditions.
