"Great White (BHP) eats Blue Whale (PetroHawk) forms new company and eats Dolphin (GGP) (variation here could be another level that represents dolphin it eats GGP = Seal)"
BHP I would have thought would be the Blue Whale and Petrohawk being the Great White. Do you know the size difference between these two. Its gi-normous. lol
