What advantages might the avian respiratory system give to the emperor penguin for over a minute about underwater?

Answer 1

The avian respiratory system of the emperor penguin, characterized by its highly efficient lungs and air sacs, allows for optimal oxygen exchange and storage. This adaptation enables the penguin to hold its breath for extended periods while diving for food. Additionally, the ability to utilize stored oxygen more effectively helps it maintain energy levels during prolonged underwater activity, which is crucial for hunting in the cold Antarctic waters. Overall, these adaptations enhance the penguin's diving capabilities and survival in its harsh environment.
