National Geographic Documentary HD 2017 - Life of Elephants

The world's largest land mammal, the adult male savannah elephant, weighs about 12,000 pounds and measures about 10 feet tall at the shoulder. The smaller forest elephant has a maximum weight of 10,000 pounds. Additionally, forest inhabitants' tusks are tiny and straight, built for navigating paths through dense vegetation, in contrast to the curving tusks of savannah elephants. The two elephants do share a robust hide (the word "elephant" in Latin is "pachyderm," which means "thick-skinned"). Elephants nevertheless need to be protected from insects and the sweltering African sun, despite the fact that their skin may be tough. An elephant can cool off and provide another layer of protection by taking a mud bath.
