Scientists working in the Brazilian Amazon have found that Giant South American river turtles (Podocnemis expansa), or Arraus, actually use several different kinds of vocal communication to coordinate their social behaviors, including one used by female turtles to call to their newly hatched offspring in what is the first instance of recorded parental care in turtles.
