Addax (Addax nasomaculatus) lives in saharan desert across North Africa. It feeds on desert grasses leaves. Its conservation status is Critically Endangered.
Fascinating facts about the Addax
- Females sport twists 55-80 cm (22-31 in) while males reach 70-85 cm (28-33 in), and one specimen was measured at a staggering 109.2 cm (43.0 in). The average horn length across the species is about 72 cm, showing a remarkable spread from modest to record-breaking sizes.
- The addax can wander the Sahara without free water. It extracts moisture from dew-coated plants and stores extra fluid in special stomach pouches, then concentrates its urine to keep every millilitre. Its pale, reflective coat bounces scorching sun rays, while a dense winter coat traps cool air. By huddling in shade by day and nesting in sand hollows at night, it trades body heat for evaporative cooling, a suite of tricks that lets it survive years where rain falls under 100 mm.
- Addax numbers have plummeted to the brink of disappearance. Fewer than 100 individuals remain in the wild, down from about 200 counted in 2010 and a historic estimate of under 500 today. The last stronghold is Niger's Termit & Tin-Toumma Reserve, yet oil-driven poaching has driven the remaining herd to the verge of extinction.
- Reproduction in the addax is a race against the desert clock. Females mature at 2-3 years, males at about 2 years, and a single calf, weighing just 5 kg (11 lb) at birth, arrives after a gestation of 257-270 days (roughly nine months). A postpartum estrus occurs after 2-3 days, and it is weaned between 23 and 29 weeks. This rapid turnover is vital for a species that must replace individuals lost to hunting and harsh conditions.
- Genetically, the addax carries 29 pairs of chromosomes, all acrocentric except the first autosomal pair, which is submetacentric. Its X chromosome is the largest acrocentric, while the Y is medium-sized. The unique banding pattern of its submetacentric pair matches the 27th and 1st chromosomes of cattle and goats, linking the addax's genome to other members of the Hippotraginae subfamily.
