If a creature is from the Elemental Plane of Water it should get the Water Subtype, otherwise it would get the Aquatic Subtype.

The Water Subtype allows it to breathe both water and usually air. It doesn't need a special ability to breathe both.

If it has the Aquatic Subtype, it breathes only water unless it also has the Amphibious Special Ability.

Special Abilities ALWAYS have a designator (Ex, Sp, or Su)


3.5 and Pathfinder sometimes use different rules. Which one is this for?
