Re: 5x08 The Hungry Earth (Grading/Discussion) SPOILERS!!
From what I can tell in the trailer, there's only one Silurian soldier speaking, who just happens to be a woman. It's possible that the Silurian military has males and females, and it just happens that their commander is female.
I'm kinda hoping they went with all women to play the Silurians. Then at least we can explain the bulgy chests as 'poison glands' or something, rather than ' the females have boobies'.
