- Slender-horned Gazelles are nomadic and traveled throughout the desert in groups of 4-10 females and young with one male.
- They live in a matriarchal society.
- Crepuscular. Their splayed hooves increase foot surface so they can walk on deep sand for extended periods of time. The lightness of their coat provides perfect camouflage in the sand.
- Slender-horned Gazelles are one of the most desert-adapted species of gazelle. They rarely need to drink water, getting what they need from dew and plant moisture.
- The reflective white coat and specially designed nasal passage allows for cooling of the blood to prevent over-heating.
- Horns are used mainly for courtship display. They have ritualized “fighting”, usually settled by threats and intimidation rather than injury.
- The main defenses are constant alertness and speed.
- Current worldwide captive populations are descended from 3 individuals. They have come through a very ”narrow genetic bottleneck” remarkably well.
- The major cause of their decline in the wild was hunting for meat and horns.
