Fennec Fox profile
Fennec foxes are the tiniest of all foxes, sporting oversized ears, a diminutive face, and a pointed snout. Their cream-colored fur is accompanied by a long, black-tipped tail, which constitutes approximately three-quarters of their head and body length.
These diminutive creatures measure around 35 to 40 cm (14 to 16 inches) in head and body length, with a tail extending 20 cm (8 inches). Their height at the shoulders stands at a mere 20 cm (8 inches).
Fennec foxes weigh between 1.36 to 1.6 kg (3 to 3.5 lbs.).
Their diet is primarily carnivorous and includes insects, snails, lizards, rodents, birds, eggs, and even plant matter like fruits and berries.
Approximately 50 days are required for incubation.
Fennec foxes reach sexual maturity at around 6 to 10 months of age.
On average, these foxes enjoy a lifespan of 10 to 12 years.
These foxes are widespread across the sandy deserts and semi-deserts of northern Africa, ranging from Western Sahara and Mauritania to northern Sinai.
Fennec foxes thrive in arid desert environments, demonstrating the ability to inhabit even the most remote sand seas. Stable sand dunes are considered their ideal habitat.
Globally, their population appears stable and is not significantly fragmented. They are common throughout the Sahara, with documented regression occurring only in the northern Moroccan Sahara, where they vanished from four specific localities near permanent human settlements during the 1960s.
IUCN: Least concern
CITES: Appendix II; legally protected in Morocco, Algeria, Tunisia, and Egypt
