The Bermuda is not filled with one monster, since no evidence is proven of The Bermuda Beast, and the fact that if it was seen, then it would have a photo being so large and could be seen near the bermuda. If it was real anyways. So the Bermuda beast could not be real being so large, but there can be small creatures. Anyways back to topic, the bermuda can contain individual monsters that wouldnt be easily seen.
