Special anatomical, physiological or behavioral adaptations:
 
Both the male and female have very strong hind legs often used for defense.  If they feel as if they are in danger, then they will rise up on their hind legs and point their horns towards their predator. 

 
 
 
 
 
 
  Interesting Facts:
 
1) The Nubian ibex has special grooming habits that include grackles.  Flocks of grackles peck at  the hides of the ibex.  They peck for parasites and any other critters that may be harmful to the ibex.  There is only one grackle per ibex and the grackles often compete for each ibex. 
2) The two main predators of the Nubian ibex are leopards and Arabian hunters. 
3) The gestation period for the Nubian ibex is 5 months and they can live up to 20 years. 

 
 
 
 
 
Comments about the Nubian ibex of the Fort Worth Zoo:
 

Natural History:

{short description of image}The Nubian ibex is a wild goat found in the Nubian Desert of northeastern Sudan, Africa.  In this area it dwells in dry desert mountainous terrain at elevations up to 8500 feet. 
Cliff Dwellers:
The Nubian ibex is very agile when it comes to maneuvering steep cliffs.  It spends much of its day moving up and down precipitous terrain.  It may come down to graze during the day and then return to the cliffs in the evening.  It is most active in the morning and late afternoon, but during the midday heat the ibex tends to lay in the shade.  In the summer it moves further up the mountain to avoid the heat.  The nubian ibex will come down to lower elevation in the winter.  It comes down the lowest in spring to reach new grass. 

 
 
 
 
Personal Observations:
 
While at the zoo I saw two male ibexes interact.  At first, they appeared as if they were going to fight but to my surprise, they were being playful towards one another.  It seemed like they were putting on a show for the visitors.  Each ibex started out on opposite sides of their housing but eventually moved closer towards the other.  As they got closer they tilted their horns towards each other and circled one another.  I thought for sure they were going to fight but they pulled away and did not do harm to one another.
