Adventures - Ask Dr. K . . . About Symmetrical Twins Dr. K met a set of twins in the Symmetry exhibit. No one can tell us apart, but sometimes I think we're exact opposites.
Some identical twins are mirror twins, and their physical traits are mirror images of each other.
If twins have hair whorls or irregular teeth patterns, they are exact opposites. In some rare cases, internal organs, like the heart, can be opposite. Hey, now I know what I look like to other people. In real life, Dr. K is Museum President and CEO, Dr. Thomas Krakauer.
