Answer 1

I’m wanting a biologist to respond but my pick is they will have developed senses to detect the things that eat them and that they eat. But the smaller the creature, the less body there is to develop complex vision systems so the question itself starts to fall down. They will have ways of sensing important things, but probably not in the way you are thinking.
