Being the Resident Elasmophile, I can help field this question - and this is the only thing I will go off topic on, and only because it can't be helped.
The Tiger Shark - Galeacerdo cuvier ***
Size - grows up to 20 feet in length.
Diet - Literally anything they can swallow, including two dolphins at a time, cans of beans, suits of armor, other sharks, and the occasional small dog.
Habitat - Typically tropical close shore and open water.
Edit: I, for one, would like to see a Tiger Shark addon.
