A goal may be scored through contact with any part of the attacker's body except a clenched fist.<ref name=water>{{cite web |url=http://www.usawaterpolo.org/media/usaplayingrules.pdf |publisher=USA Water Polo |title=USA Water Polo Rules/FINA |access-date=2008-04-29}} {{Dead link|date=September 2010|bot=H3llBot}}</ref> The goal structure in water polo is dependent upon the depth of the water.
