HTTYD Theories

I Think I Know What Female Night Furies Look Like!

Hey guys! I think I know what the female Night Fury would look like, and this is not based off a photoshop of Toothless. I think I might be onto something here.

OK, so I was watching the scene where Hiccup and Astrid are in the Hidden World watching Toothless and his Mate getting crowned.

BTW: I will call The Unnamed Light Fury Toothless' Mate, mostly because there is more than one Light Fury since they are their own unique, not-on-the-brink-of-extinction species.

And I was at the part when they are about to fly out of the cave thingy above that enormous 'Crystal Throne for The King of Dragons' when I noticed THIS:

Now it might not seem like such a big deal, but for a major HTTYD fan and addict like me:

I think that this is what a male Light Fury looks like. It has long ears, the wing membrane curves in a lot more than that of a female Light Fury, and the tail flukes and secondary wings are more of a triangle than a heart shape. 

However, some features are still the same. I noticed both genders of Light Fury still have only one pair of those secondary stubb things under the ears, or at least, that's how I see it. Does anybody know what they're called? Suggestions are welcome so I can use the word in the future. The ears are also a bit thicker or stubbier than the Night Fury. Both male and female Light Furies have the same markings on their bodies and wings. I also saw that they both have one spine down the back, starting from the middle of the neck.

I also think that, based on an image I saw of Toothless and his mate, I think that male 'Furies have larger ribcages than females. However, I'm not sure.
