💡 Interesting Facts
1
The Mexican Gray Wolf is the most endangered wolf subspecies in the world; fewer than 50 wild individuals survive in Mexico, making every breeding pair critical to recovery.
2
Extirpated from the wild in Mexico by the 1980s, the Mexican Gray Wolf was saved from total extinction by a captive breeding programme involving just 7 founding individuals; all living wolves descend from these seven.
