i know those are not the real names, i just said that we identify them in those ways....but the dna thing is not 98% its my guessing but they said (scientist) its very similer to the humans...

I believe the documentary is more true than false. In Mermaids: The body found the scientist Dr. Paul Robertson is not an actor but a real scientist who use to work for NOAA. However, the rumors of him being an actor named Andre Weideman are false.
