Platypuses are carnivorous and primarily feed on aquatic prey. Their diet includes a variety of small animals, such as:
1. **Aquatic Invertebrates:** This is a significant part of their diet and may include insects, crustaceans, and mollusks.
2. **Small Fish:** Platypuses also hunt small fish, which they capture using their webbed feet and bills.
3. **Amphibians:** Amphibians, such as tadpoles and frogs, are occasionally on the menu.
4. **Aquatic Worms:** Platypuses may feed on aquatic worms and larvae.
They are skilled hunters and rely on electroreception to detect the electric signals produced by the muscle contractions of their prey. Their webbed feet are used to paddle through the water while hunting, and their bills are equipped with sensors that can detect prey even in murky waters. The platypus hunts underwater, storing prey in cheek pouches and returning to the surface to chew and swallow.
