Crab-eating (Savannah) Fox

The crab-eating fox, also known by names like the forest fox, wood fox, bush dog, or maikong, is an intriguing medium-sized canid found in central South America. Despite its name, it is not closely related to true foxes; instead, it belongs to the genus Cerdocyon. This species first appeared during the Pliocene epoch and is a member of the Canini tribe, making it a relative of the genus Canis.

The crab-eating fox inhabits a variety of environments, including savannas, woodlands, forests, and shrubby thickets. However, it tends to avoid rainforests and wide-open grassy savannas.

Genetically, this fox has 74 diploid chromosomes and is the sole living member of its genus, Cerdocyon. It sports a greyish-brown coat with reddish markings on its face and legs, black-tipped ears and tail, and typically weighs between 10 to 17 pounds. It is a nocturnal creature, most active at dusk, with a diet that includes crabs, lizards, and even birds. Interestingly, the crab-eating fox is monogamous and forms hunting pairs and territories during the dry season.

Reproduction occurs twice a year, with the female usually giving birth to one or two litters. The fox's diet is quite varied, ranging from crabs and insects to rodents, birds, fruits, and carrion, with seasonal variations.

Fortunately, the crab-eating fox is not currently at risk of extinction. The IUCN lists it as "Least Concern." There are five recognized subspecies, each differing slightly in size and fur coloration, spread across South America. These foxes play a crucial role in their ecosystem by helping to control rodent populations and harmful insects.
