I have what I believe is a Ghana Giant female, purchased from Outback. She was imported in 2010, and laid a clutch of 13 for me. Unfortunately, I was lacking in experience and no hatchlings survived.
Here are a few photos of her and my large "normal" girl.
This is the two of them side by side.
This is a closeup of their heads. Note the difference in size and shape of the head on my Ghana girl on the left.
Another closeup, the Ghana is on the right. Both girls are nearly 6 feet long, and the light female is actually almost 800 grams heavier than the dark Ghana girl is.
