Sep 18, 2023 · Watch on. Navigational Tools: How Animals Use Horns for Orientation. Horns can also serve as navigational tools for many species of animals. Some animals, such as antelopes and gazelles, use their horns to help them navigate through dense vegetation or over rough terrain.
The “horn” of a rhinoceros is composed of fused, heavily keratinized hairlike epidermis. Horns serve as weapons of defense against predators and of offense in battles between males for breeding access to females.

True horns are composed of a bony core covered by keratinous material. Bones are semi-rigid, porous, mineralized structures that consist of cells in a hard matrix and that form part of the endoskeleton of vertebrates. Although externally they may appear to be solid structures, in reality they are composed of living bone tissue interlaced with blood...
Animals utilize their horns in a variety of ways. They may be used in fighting, whether for defense from predators or for fighting members of their own species for territory, dominance, or mating priority. Horns may be used in feeding, such as to root in the soil or to strip bark from trees. Some animals with true horns use them for cooling, the bl...
Horns have been used by people for many purposes throughout history. Some bovid horns are used as musical instruments, for example the shofar, which is often made from the horn of a ram (although any animal except a cow or calf can be used) and is used for Jewish religious purposes. The shofur is referenced as far back as the book of Exodus. These ...

When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system, and a root system.
For true animals, the first step is ingestion, the act of taking in food. This is followed by digestion, absorption, and elimination. In the following sections, each of these steps will be discussed in detail.
Plants. Although research into the flora of the Horn of Africa is still ongoing, the best possible estimates are that there are about 5,000 species of vascular plants in the region, just over half of which—about 2,750 species —are endemic. There are strong concentrations of endemic species in northern Somalia and in the Socotra Archipelago.
