Manual of the Planes
Acid (Ex): An ooze paraelemental's muck is highly acidic and can rapidly dissolve organic material and metal. Any melee hit deals acid damage. The paraelemental's acid deals 40 points of damage per round to metal or wooden objects. Armor or clothing dissolves and becomes useless immediately unless it succeeds at a Reflex save (DC 25). A metal or wooden weapon that strikes an ooze paraelemental also dissolves immediately unless it succeeds at a Reflex save.
If an ooze paraelemental successfully grapples an opponent, the opponent's armor must likewise make a Reflex save at a -4 penalty or dissolve into uselessness.
Ooze paraelementals relish combat against most humanoid foes, because their acid can melt weapons.

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.
