The Shark Tank is a very very large arena boxed in by unbreakable glass and filled halfway up with water, salt water. There are nice sized pieces of lands in it that can allow for a clashing to happen, but the islands start to sink. It sucks to be the deadmen, because their are angry sharks inside the water, at least 4 great whites and other sharks vary. This is meant to be a free for all holding up to 8 people.
