Bovidae are any of almost 140 species of cloven-hoofed, ruminant mammals with characteristic unbranching horns covered in a permanent sheath of keratin. The family is widespread, being native to Asia, Africa, Europe and North America. Some are thick-set and muscular; others are lightly built, with small frames and long legs. All bovids have four toes on each foot they walk on the central two hooves, while the outer two hooves are much smaller and rarely if ever touch the ground.
Tokyo Jungle features several members of this family.
