Crab Facts: Claws, Shells & Secret Behaviors
Crabs are crustaceans found on every continent with over 7,000 species. Discover why crabs walk sideways, trade shells, and grow claws stronger than jaws.

Foxes are intelligent canines found worldwide with 12 species. Discover fox behavior, hunting techniques, habitats, and how they thrive in diverse environments.
Foxes are small to medium sized canines known for their intelligence and adaptability. With 12 true fox species distributed across the globe, these clever animals thrive in diverse habitats from Arctic tundra to urban cities.
Foxes have slender bodies, pointed ears, and distinctive bushy tails. Their tails, called brushes, provide balance while running and warmth during cold weather. Red foxes display various color morphs including red, silver, and cross patterns.
Foxes inhabit nearly every continent except Antarctica. Arctic foxes survive in some of Earth's harshest climates where temperatures drop below negative 70 degrees Fahrenheit. Most fox species are territorial and mark boundaries using scent glands and urine.
Foxes are omnivores with varied diets depending on season and location. They primarily hunt small mammals like mice, voles, rabbits, and squirrels. Their hunting technique involves slowly stalking prey, then leaping high into the air and pouncing with front paws.
Foxes are primarily solitary hunters but may form small family groups. Red foxes are mostly nocturnal and crepuscular, being most active during dawn and dusk. They communicate using over 40 different vocalizations including barks, screams, and howls.
After a gestation period of 49 to 55 days, females give birth to 4 to 6 kits in underground dens. Their eyes open after about 2 weeks. Young foxes leave the family group at 6 to 12 months of age to establish their own territories.
Foxes have lived alongside humans for at least 16,000 years, with evidence of domestication attempts.
The Russian fox experiment beginning in 1959 revolutionized understanding of animal domestication.
Fox hunting became a major social ritual in Britain, shaping landscape and culture for centuries.
Foxes appear in folklore worldwide as clever tricksters, from Aesop's fables to Japanese kitsune.
Research found foxes have over 40 different vocalizations, including screams that sound disturbingly human.
Studies showed red foxes have the largest natural distribution of any wild carnivore, spanning most of the Northern Hemisphere.
Scientists discovered foxes may use magnetic fields to hunt, a sense found in few other mammals.
Urban ecology research revealed city foxes are evolving different skulls from their rural counterparts.
Foxes feature as trickster figures in the folklore of cultures across Europe, Asia, and North America.
Japanese culture includes kitsune, fox spirits that can shapeshift and possess humans.
Fox hunting bans in Britain sparked major political and cultural debates about tradition and animal welfare.
The viral song 'What Does the Fox Say?' brought fox vocalizations to global attention.
Before urbanization accelerated, foxes lived primarily in forests and countryside. They were hunted for fur and sport, and seen mainly as pests that killed chickens. Rural fox populations remained relatively stable for centuries.
Foxes have become successful urban colonizers, adapting to cities worldwide. They eat garbage, pet food, and anything available, thriving alongside millions of humans. The Russian fox experiment revealed how quickly domestication can occur, while wild foxes continue evolving to exploit human environments.

Yes, foxes belong to the Canidae family, which includes dogs, wolves, and jackals. However, foxes and dogs separated evolutionarily about 7 to 10 million years ago. Foxes cannot interbreed with dogs and have different chromosome numbers. They display more cat like behaviors than other canids.
