How do Au'ra hear?

[GMERC]

Well how do lizards have kids? They lay eggs....!

Little Au Ra hatchlings must be so cute!

Well there is also the possibility of little Au Ra tadpoles!

Yes I realize the irony that me as Au Ra not knowing how we are born... My Au Ra parents never explained it to me how it works!

Au Ra are not lizards, just as Miqo'te are not cats. There is almost no chance whatsoever that any of the playable races in this game have anything but fairly ordinary human births.
