does anyone know what dragon types there are.

Ice type,Fire type,Water type,Forest type

If you're talking about elements, the ones I know of are air/wind, earth, fire, water, ice, nature, lightning, and darkness.

But if you're talking about actual types, then there are a lot. I know some of you might remember a few of these types from Harry Potter or so, but there were Peruvian Vipertooth, Chinese Fireball, Swedish Shortsnout, Welsh Green, Hungarian Horntail, Night Fury (I put this for you fellow HTTYD fans), and a few others I can't remember the names of.

there are the elements :
fire, water, wind/air, earth, spirit, light, dark,
then there are the flying dragons, water dragons and th the lung dragons/Chinese dragons
