Both have the best respiratory system for the particular job. The harvester ant has spiracles. Their needed oxygen comes directly from outside air. As a result insects are restricted to a relatively small size. They do not need to produce red blood cells so they can live in that niche. A poison dart frog is a larger animal. It has lungs. Because it has lungs and uses hemoglobin, it can provide oxygen to a larger body. Each animal has the best respiratory system for the necessary job.
