Elephants produce two types of vocalization by modifying the size of the nostrils as air is passed through the trunk. Author of numerous scientific and popular publications on elephants and other proboscideans.

They also protect the sensitive trunk, which is tucked between them when the elephant charges. Elephants have six sets of cheek teeth (molars and premolars) in their lifetime, but they do not erupt all at once. They are found most often in savannas, grasslands, and forests but occupy a wide range of habitats, including deserts, swamps, and highlands in tropical and subtropical regions of Africa and Asia.

At the beginning of the 21st century, fewer than 50,000 Asian elephants remained in the wild. An Asian elephant most often curls the tip of its trunk around an item and picks it up in a method called the “grasp,” whereas the African elephant uses the “pinch,” picking up objects in a manner similar to that of a human’s use of the thumb and index finger.
