Platypus

These bizarre, duck-billed, egg-laying mammals have an incredible sense of electroreception that is similar to the sixth sense of sharks. They use electroreceptors within the skin of their bills to detect the electrical field that gets generated when their prey contracts its muscles.

A platypus swings its head from side to side while swimming as a way to enhance this sense. The bill is also lined with mechanoreceptors, which give the animal an acute sense of touch and make the platypus' bill its primary sense organ.
