The Nubin Ibex is from Sudan, is light brown with a dark dorsal stripe and is a fairly small animal weighing about 100 lbs.  The horns of the Nubian Ibex have pronounced knots on the forward edge of the horns and grow up, back, and then hook back in.  He is similar to the Siberian Ibex but much smaller.  Unlike the Siberian though, the Nubian is a hardy animal and does well in Texas.
