The Family Canidae includes dogs, wolves, foxes, coyotes, jackals, and related species—about 35 living species found worldwide except Antarctica. Canids are typically slender, long-legged mammals adapted for running and endurance hunting. They have sharp teeth for tearing meat but are generally omnivorous, eating both animal and plant matter. Most are social, often living in pairs or packs with complex communication through vocalizations, scent marking, and body language. As adaptable predators and scavengers, canids play important roles in ecosystems and have close ties to humans through domestication of the dog (Canis lupus familiaris).
