Underwater hockey is exactly what it sounds like. It's the game of hockey that is normally played on ice skates altered to be played in the water. You may be wondering how exactly this works seeing as normally all players are upright on their feet during play.

Well, the gear that is required for this sport is quite unique. Players are of course in swim suits and wear swim caps to protect their ears and goggles to protect their eyes. Also, each swimmer is allowed to wear gloves on both hands if they choose to as well as a mouth guard. All players are also provided with a gas mask so they can stay underwater for the duration of the game. Each player also uses a stick that tends to be quite short. The puck used for underwater hockey is quite similar to that used in regular hockey but it is made of lead so it sinks to the bottom of the pool.

As for the rules of the game. They are very similar to ice hockey. There are 6 players in play at all times unless a penalty is received by a player. The goalie blocks the goal posts at all times. One of the big differences is that there are normally two halves that are between ten and fifteen minutes long depending on the league the players are in.

Then there's the referee's for the game. It's handled a little bit differently then in most sports. They keep a referee in the water to observe more closely the players and makes sure they're not breaking any of the rules. Then, they have another referee on the deck or pool side watching from above. This is because it is easier for them to see if someone crosses a boundary from above then in the water. There are normally between 2 and 3 referee's watching each game.
