Fleas are small. Bacteria too. Can fleas see bacteria?

Answer

G’day Ciel,

No! Fleas are small, but they are still enormously larger than bacteria. It’s not because you’re big or small that you can see big or small things. An elephant and a mouse both see the same little things because they have equally good eyes, but bacteria are certainly not among them. You need a very good microscope to see them.

Greetings,

Rudy
