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.
Shark lifespan varies by species. Although most of them live 20 to 30 years in the wild, there are some that live much longer than others. For example, the spiny dogfish has one of the longest lifespans on Earth with more than 100 years, while the blue shark in the wild has an average life expectancy of 15-16 years.
