The platypus’ duck-like bill contains electroreceptors that detect electric fields generated by the muscular contractions of prey. This allows them to hunt underwater with eyes, ears, and nostrils closed. It’s a highly specialized sensory system combining touch and electricity detection. Platypuses can locate insects, worms, and small crustaceans buried in mud. Electroreception is rare among mammals but common in aquatic species like sharks. This adaptation enables nocturnal and underwater foraging. It makes their hunting extremely efficient even in murky waters.
Electroreception shows sensory innovation in mammals.
It allows the platypus to exploit ecological niches that other predators cannot.
This capability is key to their survival in Australia’s rivers and streams.
