While diving, platypuses seal off eyes, ears, and nostrils to prevent water entry. They rely entirely on bill sensors to locate prey. This allows efficient hunting without visual cues. Underwater closure prevents infections and keeps sensory organs safe. This adaptation enables hunting in murky water. Platypuses can adjust to water temperature and current without visual input. It maximizes foraging success while minimizing injury.
It demonstrates sensory specialization for fully aquatic hunting.
Closing sensory organs allows the platypus to feed in complete darkness.
It ensures survival and efficiency in varied aquatic environments.
