For the sake of journalism, and the good photographers at Getty, I will tell you that above, you'll see Evanthia Makrygianni and Despoina Solomou of Greece performing their technical routine in duet synchronized swimming, and below, Marie-Pier Boudreau Gagnon and Isabelle Rampling of Canada. (Why do they all have such amazing NAMES!?)
To me, however, it just looks like they're performing Aida in fancy swimsuits.
