African elephant

life science Maturity 11-13 Next article →

African elephants are massive, social herbivores belonging to the genus Loxodonta. This genus includes two distinct living species: the African bush elephant (Loxodonta africana) and the smaller African forest elephant (Loxodonta cyclotis).

These animals are vital to the ecosystems of Sub-Saharan Africa. However, both species face serious threats of extinction. The bush elephant is currently listed as endangered by the IUCN Red List. The forest elephant is even more at risk, being classified as critically endangered. These declines are driven by habitat loss, habitat fragmentation, and poaching for the illegal ivory trade.

Physical traits help distinguish these two species from one another. While both have grey, folded skin and sparse dark hair, their shapes differ. The African bush elephant has a concave back and is much larger. In contrast, the forest elephant has a nearly straight back and a smaller frame.

Their skulls also show differences, with the forest elephant having a shorter, wider head and a concave forehead. Their ears and tusks also vary in size and color. These physical adaptations help them thrive in their specific environments, whether in scrublands or dense rainforests.

The elephant's trunk is a highly specialized organ. It is a prehensile elongation of the upper lip and nose. This organ is controlled by an incredible number of muscles, estimated between 40,000 and 60,000.

Because of this muscular density, an elephant can use its trunk to lift about 3% of its own body weight. The trunk is sensitive and is primarily controlled by the trigeminal nerve. Elephants use this tool for many essential tasks. They use it to smell, touch, drink, and feed. They also use it for dusting, producing sounds, and even as a snorkel when swimming underwater.

Elephants also possess tusks that grow throughout their entire lives. Both males and females have these tusks, which emerge from temporary teeth called tushes.

The tusks are composed of dentin, which forms small diamond-shaped structures in the center. As the tusk grows, these structures become larger toward the outer edge. Elephants use their tusks to strip bark from trees, dig for roots, and defend themselves. Their teeth also play a crucial role in survival. They have four molars that move forward as the front ones wear down. An elephant can replace these teeth four to six times. However, once the last molars are lost, usually between 40 and 60 years of age, the elephant may die of starvation.

The name Loxodonta has a specific scientific origin. It comes from the Ancient Greek words "loxos," meaning slanting or crosswise, and "odous," meaning tooth.

This refers to the unique lozenge-shaped enamel found on their molar teeth. This shape is a key way to tell them apart from Asian elephants, which have rounded enamel. The history of their classification is quite long. Johann Friedrich Blumenbach first described them in 1797. Later, Frédéric Cuvier proposed the genus name Loxodonta in 1825. In 1900, Paul Matschie identified the forest elephant as a separate species after studying specimens from Cameroon.

Fossil evidence shows that the Loxodonta lineage is very old. The oldest known species, Loxodonta cookei, lived around 7 to 5 million years ago.

Genetic studies show that the bush and forest elephants split from each other between 2.6 and 5.6 million years ago. While they are separate species, DNA shows they hybridized in the past. This happened in the transition zones between savannas and forests. Interestingly, the extinct European straight-tusked elephant (Palaeoloxodon antiquus) was also closely related to African elephants. DNA shows that this extinct genus even shared significant ancestry with the African forest elephant.

Social structures are central to elephant life. They live in family units led by an older female called a matriarch.

These groups include adult cows, their daughters, and subadult sons. While females are very active in the group, males often live more independently. However, new research suggests that bulls still hold important ecological knowledge that helps the herd find food and water. Elephants also have unique communication skills. They can distinguish between hundreds of low-frequency infrasonic calls.

These sounds are too low for humans to hear, but they allow elephants to communicate across vast distances.
