What animals would we be in seaworld

So, Maia sits in the tub and says:
"Mom, I'm a mermaid."
"You are?" I say.
"Yes," she answers and pointing at her 9 month-old sister splashing all over the place, "and baby is an octupus. .... and Daddy ... Daddy is a whale."
"ah nice. I'm sure he'd be thrilled to hear that," I comment, "and what am I?"
"you, mommy.... you are...a shark."

I'm not sure if I would have rather been a whale in my daughter's projection of our characters into the marine world but a shark? Come on, I'm not that bad.
I'd see myself more like a dolphin. In fact, if there is such a thing as reincarnation then I would like to be reborn as a dolphin (preferrably the type, who doesn't hang around with tuna too much).
