An Elephant.
The idiom "elephant in the room" is not as common as the idiom "800-pound gorilla in the room", but both have similar connotations. The "elephant" applies to some dominant element, situation, or eventuality that everyone is aware of but that is either ignored or barely acknowledged. For example, shareholders at a meeting could be discussing the fine points of a merger, knowing all too well that the government was threatening to shut down the operations of one of the companies involved. An example sentence : "The elephant in the room at the teacher's conference was the new mayor's promise to remove inefficient teachers." (see the related question)
Elephants are in a herd.
