 Leviathan  is a title given to any creature big enough. They do not have to be at the top of the food chain because herbivores like the Reefbacks and the Sea Treaders are classified as leviathans.

I think that the PDA says that because they are massive, only one Leviathan can hunt another Leviathan.
