Elephant Family

The matriarch leads her family across the Masai Mara on their never ending search for food. Elephants can eat up to one fifth of their body weight each day and will eat for up to 20 hours out of every 24.
African elephants are bigger than Asian Elephants. Males stand 3.6 m (12 ft) tall at the shoulder and weigh 5,400 kg (12,000 lb), while females stand 3 m (9.8 ft) and weigh between 3,600 and 4,600 kg (7,900 and 10,000 lb). However, males can get as big as 6,800 kg (15,000 lb).
Elephants have four molars; each weighs about 5 kg (11 lb) and measures about 30 cm (12 in) long. As the front pair wear down and drop out in pieces, the back pair shift forward and two new molars emerge in the back of the mouth. Elephants replace their teeth six times. At about 40 to 60 years of age the elephant no longer has teeth and will likely die of starvation, a common cause of death.
Their tusks are teeth; the second set of incisors become the tusks. They are used for digging for roots and stripping the bark off trees for food, for fighting each other during mating season, and for defending themselves against predators. The tusks weigh from 23–45 kg (51–99 lb) and can be from 1.5–2.4 m (5–8 ft) long. Unlike Asian elephants, both male and female African elephants have tusks
Poaching significantly reduced the population of elephants in certain regions during the 20th century. An example of this poaching pressure is in the eastern region of Chad—elephant herds there were substantial as recently as 1970, with an estimated population of 400,000; however, by 2006 the number had dwindled to about 10,000. The African elephant nominally has governmental protection, but poaching is still a serious issue.
