More commonly known as the Brazilian Snake-necked Turtle or Maximilian's Snake-necked Turtle, this species of turtle is native to Brazil. This species is the type species for the Hydromedusa genus. In other words, this genus is directly linked to this species of turtle, so, if there are any revisions, the genus will stay constant with this species. Later I will add their SCL, synonymy, holotype, type location, IUCN listing, and images!
