Horse anatomy. The horse has a sesamoid bone called the navicular bone, located within the hoof, that lies on the palmar aspect of the coffin joint between the second phalanx and third phalanx (coffin bone). The navicular bone in the horse is supported by the distal sesamoidean impar ligament and two collateral sesamoidean ligaments.
Young males are at first leave, jostling with the older jaguars until they succeed in claiming a territory. Typical life span of the jaguar in the wild is estimated at around 12 â 15 years. In captivity, the jaguar lives up to 23 years, placing it among the longest living cats.
Humans are the main threat to the jaguar. A jaguar seldom, if ever, attacks humans unless it is cornered. Humans hunt the jaguar for sport, for its spotted hide, and to protect their domestic stock. The jaguar is endangered because it is hunted for its fur, and farmers kill the jaguar because it killed their cattle.Jaguars are reputed to be so destructive of cattle and horses that the larger Mexican ranches retain a 'tiger hunter' to kill them or at least drive them away.ome jaguars are even white. The jaguar's coat on its side and back is spotted with large black rosettes, each consisting of a circle of spots surrounding a central spot. The spots on its head, legs, and underside are solid black. An adult male jaguar may be four to seven feet long, excluding the long tail.
