We have all the senses that you have, which are taste, touch, smell, sight and hearing. However, we have also a sixth sense, that you do not have and that is - we can sense weak electrical signals made by the muscular movement of our prey.

This allows us to find our prey easily, together with our strong eyesight, which enables us to see in colour and in the dark, a good sense of smell and our terrific hearing ability. So even if a fish is clever enough to hide, and doesn't move either, we can still detect its moving heart with our super strong senses and find it!
