Answer:
What animal dwells in water and best known for its work ethic?
What goes in the water black and comes out red?
I am the only animal to have the same Latin and common name.
What does a cat have that no other animal has?
My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from Noah's ark won quick release.
Of these things - I have two. One for me - and one for you. And when you ask about the price, I simply smile and nod twice.
