You can fight it two times. Not sure if answered before but you can.

This one, I would assume, is the one that appears in the "Frontier Caverns" later on through a quest in the game. I can't remember when you get it, I think it's before the "Final Battle" quest or just straight after, either way you can fight the regular black hydra twice-ish(meaning the first battle where you take the head to the duke and the second time in Frontier Caverns via the quest)

The other type is indeed the Arch-hydra, which is the white one in Everfall.
