These strange underwater pyramid structures at a depth of two thousand meters were identified with the help of a sonar. Studies of other structures like Yonaguni in modern day Japan have allowed scientists to determine that the two giant pyramids, apparently made of something like a thick glass, are really impressive - each of them is larger than the pyramid of Cheops in Egypt.
