Clip Description

The duck-billed platypus is one of nature’s strangest looking animals. It has a bill and webbed feet like a duck, the fur and body shape of an otter and a beaver-like tail. They are one of the few living mammals that are venomous.

In this fascinating clip, we see a platypus hunting for prey in a river. With over 40,000 electrical receptors in its bill, the platypus uses this unusual body part to detect the tiny electrical signals that are given off by the muscles of prey animals. Why do you think duck- billed platypuses frequently bump into rocks that are on the riverbed? Watch the clip to find out.
