Inferior Dragon Abilities: Yu lungs lack the standard lung dragon abilities of invisibility and alternate form.

Water Breathing (Ex): Yu lungs breathe water. They are able to exist on land for only 1 hour before they begin to suffocate (see Suffocation in Chapter 3 of the DUNGEON MASTER's Guide.)

Spirit Subtype

Spirit creatures include some fey and elementals (nature spirits), outsiders (celestial spirits), undead (ghosts and ancestors), and even dragons. Spirit creatures are nor necessarily incorporeal, despite their name - in the worlds of Oriental Adventures, some spirits are as much flesh and bone as humans are. The only game effect of the spirit type modifier is that spirit creatures are all affected by spells such as commune with greater spirit, invisibility to spirits, and protection from spirits.

Water Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Water. Creatures with the water subtype always have swim speeds and can move in water without making Swim checks. A water creature can breathe underwater and usually can breathe air as well.
