No offense Cbachura, but you really have no idea what you're talking about... Animals aren't classified in groups by their behaviour, they are classified by biological similarities. Birds fly right? Well, ostriches and penguins don't fly, yet they are still birds, because they have beaks, wings, feathers, scaly legs, lay eggs etc.

Just because a lot of leviathans "swim" doesn't mean that's the defining characteristic of their class. Nor is it using water element. Those have nothing to do with their group, they are just thier natural abilities, which happen to more or less coincidentally overlap in a certain group.

And Khezu not having anything in common with other flying wyverns? What are you smoking? They have identical skeletal builds, apart from Khezu not having eyeholes. Ukanlos/Akantor is a more fair example, because they don't have wings and stand on all fours, but I think that's just because they are outdated, they should be reclassified as either fanged wyverns or a new class.

Now, I'm not an expert in biology so I might have made some mistakes in my comment, but it's pretty darn obvious that monsters aren't put in groups together just because they use water or they swim.

Sorry for getting a bit worked up, but I'm pissed off with this stupidity
