The African elephant (Loxodonta africana) is distinguished by its remarkable trunk, a fusion of the nose and upper lip, endowed with extraordinary dexterity and strength. This multifunctional appendage serves as a respiratory organ, a scent detector, a tactile sensor, a manipulator for food and objects, a means of communication through sound, and a tool for social interaction and environmental modification.

Structure and Mechanics
The trunk contains over 40,000 muscles, enabling feats of precision and power without any bone structure. African elephants can uproot trees, pick a single blade of grass, or delicately caress a calf with the same organ. The trunk also houses two finger-like projections at the tip, facilitating fine motor skills unique among proboscideans.

Sensory Functions
Equipped with olfactory receptors, the trunk excels at detecting scents up to several kilometers away, essential for locating water and food. It also serves as a tactile organ, conveying information about texture, temperature, and vibrations—crucial for social bonding and environmental awareness.

Communication
Trunks generate low-frequency sounds (infrasound) that travel long distances, facilitating communication across herds. They are also used for vocalizations like trumpeting and rumbling. Additionally, tactile signals via trunk-to-trunk contact reinforce social bonds and convey emotions.

Environmental Interaction
Elephants manipulate their environment by using trunks to uproot vegetation, dig for water, and spray dust or water for bathing and cooling. This tool-like functionality is a key reason elephants are considered ecosystem engineers.

Conclusion
The trunk of Loxodonta africana is much more than a nose; it is a sophisticated and versatile organ that plays a vital role in the elephant's survival, social life, and environmental impact.
- A multifunctional organ essential for survival, socialization, and environmental engineering.
- Contains about 40,000 muscles, enabling both delicate and powerful actions.
- Functions in respiration, olfaction, touch, manipulation, communication, and environmental modification.
