Maybe, what they meant about an animal being a "mythical" zoan is that sort of creature holds distinct powers or traits for example, the phoenix's regeneration powers and the buddha's golden build. Whatcha think?

For Hydra, maybe it might fall under the "snake" category. Remember Boa Sandershonia's attack, Yamata no Orochi. Well, dragons might fall under the Sala-Sala Fruit, the same as Smiley. And dragons, might not be mythical in OP world, but having a human ate a Dragon-Dragon Fruit (ifever there is) will be good. The Sphinx might fall under the Neko-Neko no Mi.
