The Crab-eating Fox (Cerdocyon thous), also known as the forest fox, is a medium-sized canid found in central South America. It has a slender body, a bushy tail, and a coat that varies in color from gray to brown with a hint of reddish or yellowish tones. Adult crab-eating foxes weigh between 4.5-7.7 kg and measure about 60-70 cm in body length, with a tail length of approximately 30-35 cm.
These foxes have a pointed muzzle, large ears, and a keen sense of smell. Their limbs are relatively short, but they are agile and capable of moving quickly through their diverse habitats.
Hábitats y distribución
The crab-eating fox thrives in a variety of habitats across South America, ranging from tropical and subtropical forests to savannas, grasslands, and even semi-arid regions. It is particularly adaptable and can also be found in regions undergoing seasonal flooding, such as the Pantanal, the world's largest tropical wetland area. Occupying such diverse environments allows the crab-eating fox to exploit a wide range of food resources, from fruits and insects to small vertebrates and, as its name suggests, various crustaceans. Geographically, this versatile canid is distributed across much of northern and central South America. Its range extends from Colombia and Venezuela in the north down through Brazil, Bolivia, Paraguay, Uruguay, and into northern Argentina. Its adaptability to different habitats and food sources ensures its widespread presence within these regions, maintaining a stable population even in changing environmental conditions.
Comportamiento y reproducción
The crab-eating fox exhibits monogamous pairing, where males and females form stable pairs that often last for life. Breeding typically occurs once a year, with a gestation period of around 56 days, resulting in the birth of 2 to 6 pups. Both parents participate in rearing the young, showcasing a high level of biparental care that includes feeding, grooming, and protecting the pups from predators. Socially, the crab-eating fox tends to live in small family groups, usually consisting of the monogamous pair and their offspring. These foxes are primarily nocturnal and crepuscular, engaging in a highly territorial yet cooperative dynamic. An interesting reproductive strategy includes flexible birth timing; they can adjust mating periods based on environmental conditions, ensuring that offspring are born during times of food abundance, maximizing survival rates.
Dieta

Estado y esfuerzos de conservación
The conservation status of the Crab-eating Fox (Cerdocyon thous) is classified as Least Concern according to the IUCN Red List of Threatened Species. Population trends for the species are generally stable, though localized declines can occur due to habitat fragmentation and human activities. Primary threats include habitat loss from agricultural expansion, hunting, and competition with domestic animals. Roadkill incidents also pose a significant risk. Conservation measures for the Crab-eating Fox primarily focus on habitat preservation and reducing human-wildlife conflict. Efforts include the creation and maintenance of protected areas, as well as community-based initiatives aimed at promoting coexistence. Environmental education programs are implemented to raise awareness about the species and its ecological role, aiming to reduce persecution and encourage conservation-friendly practices.
