I have a picture from a guy in the Philapines of a pair of Somalian leopard tortoises he has had for 15 years. He tells me the female weighs 380 pounds and I believe it based on the photo. She is larger than any big male sulcatta I have ever seen and is very high domed as well. The male is smaller but still a big tortoise.

Bill Zovickian has always said that (some) Leopard tortoises were the largest mainland tortoises not the G. sulcatta. I think he is right.
