[Chentvin]

You find us in darkness, but never in light.
You find us in daytime, but never it night.
In the deepest of shadows, we hide in plain sight.
What are we?

Bats... or moles?

What can be caught, and heard, but never seen?

Air (can be heard when there is wind).

They call me a man, but i don't have a wife.
I do have a body, but i do not have life.
I do have a mouth, yet i have no breath.
Water brings me life, and light brings me death.
What am i?

Gremlins??? :P
