What kind of animal would you like to be?

This was a question from an interview:

If you could be an animal, what would you like to be???

My answer:
"I think I am definitely a sheep, I sacrifice myself a lot.
But, if I could chose, I would like to be a dolphin.
They are smart, big fish, but not the predator type, they can fight a shark, and they help humans.
They also have this x-ray type of vision, and can shrink a tumor." )

Please share your thoughts on this....and what kind of animal you would like to be...
