This shows the difference between a male and a female Neodammerai.
As you can see, the difference is the rekoi.
The male's rekoi is up in quill like form and the female's are down like bangs.
Males are also taller and have a flat chest, while females have large breasts and 4 toes on their feet.
(The females breats are for breast feeding a child but more to show indication of health.)
They also have the same sexual organs as humans...
I'm not going in detail about that now..
