population dynamics within various forest habitats. However, like many other species that live in tropical rainforests, the titan beetle is threatened by habitat degradation, deforestation, and climate change, all of which can have a substantial influence on its distribution and population levels. Conservation activities focused at maintaining their natural habitats are therefore critical for assuring their continued survival.

The constraint on the diffusion of oxygen into the tracheal system limits the maximum body size attainable, as there will be a point where some tissues in the body will not receive oxygen at

Despite their broad distribution throughout South
America, the titan beetle is secretive and rarely seen due to its nocturnal habits and cryptic behavior. As a result, thorough surveys and research are required to acquire a better knowledge of its distribution throughout its range, as well as
