How does the opah's ability to maintain higher body temperatures benefit its hunting?

Answer

It enables the opah to actively hunt and see clearly in the cold, dark depths

The internal temperature regulation mechanism, which keeps the opah warmer than its environment, is a critical adaptation directly supporting its predatory lifestyle. By maintaining a warmer internal environment, the fish's muscular system functions with greater efficiency, allowing for sustained, active pursuit of prey. Crucially, keeping the eyes warm ensures that vision remains sharp and functional even in the extremely cold and light-deprived conditions characteristic of the deep sea habitat where its prey resides. This combination of optimized motor function and clear vision provides a distinct advantage in locating and capturing food compared to ambient-temperature-regulated predators in the same zone.
