An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Elephantidae is a family of large, herbivorous proboscidean mammals which includes the living elephants (belonging to the genera Elephas and Loxodonta), as well as a number of extinct genera like Mammuthus (mammoths) and Palaeoloxodon.
When looking at an African elephant and an Asian elephant side-by-side, you can really tell the differences in their head shapes and tasks. African elephants generally have much larger tusks than ...
Before the hunt began, ritual acts of singing and dancing were performed by the community to support the success of the hunt. These hunters often went into the forest without food, living off of wild honey and vegetables, smearing themselves in mud, elephant dung, and charcoal made from certain plants to disguise their scent from the elephants.

Bull elephants in musth have killed keepers/mahouts, as well as other bull elephants, female elephants, and calves (the last usually inadvertently or accidentally in what is often called "herd infighting").

The forehead of the elephant is actually a structure that protects the pollen from the weather called a galea, and ranges in size from 1.5–3 millimeters, and extends into the long slightly coiled beak that resembles the elephant's trunk of 5–18 millimeters; the lateral lobes of the flower resemble an elephant's ears. This "remarkable ...
Cephalization is an evolutionary trend in animals that, over many generations, the special sense organs and nerve ganglia become concentrated towards the front of the body where the mouth is located, often producing an enlarged head.
Sicily and Malta were inhabited by two successive waves of dwarf elephants derived from P. antiquus, which first arrived on the islands at least 500,000 years ago. The first of these species is P. falconeri, which is one of the smallest dwarf elephant species at around 1 metre (3.3 ft) tall, and was strongly modified from its ancestor in numerous aspects, which lived in a depauperate fauna ...
