In the Belly of a whale?

When my boyfriend was in university he helped dissect a whale. So if by expedition you mean "cutting open and getting covered in dead whale parts" yes, there has been. I also don't know where you heard that you could crawl through a whales aorta but you can't. Their hearts are big but not that big.

Once upon a time there was this pirate. This pirate had been out sailing all day long drinking wine. Then out of no where this whale appeared. As the pirate looked at the whale he noticed the blow hole on top of the whale then the drinking pirate..... well I'll stop there, by the way, the second answer is correct.

Hopefully in a shark cage at the bottom of the ocean.

A sea turtle.  You just float around, laxin' in the water, a lot of things can't or won't eat you, because of your shell and you get to be in the water (my favorite place) 24/7.  Check out a sea turtle next time you see one -- it's the ultimate zen!

There's oil under the water. I am not sure how oil is made, I assume it has to do with the fossils of animals - in this case mammals, fish, and plants.

A tiger.  Hippos don't move very fast out of the water.
