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.
Male and female jaguars live together only during the mating and pregnancy season. After a gestational period of 95 to 110 days, the female gives birth to one to four young cubs; they usually have 2 cubs. New born jaguars weigh between 1 1/2 and 2 pounds (.7 and .9 kilograms).
