A large selection of wallpapers and images featuring animals. This broad kingdom of creatures contains mammals such as ourselves, reptiles, amphibians, fish, birds, insects and many other families of organisms.
The word animal derives from the latin Animalis meaning living being or having soul. Other related words such as animate or animation are also derived from this word. Animals are a large family of creatures defined by some common characteristics. They are heterotrophs - they ingest other organisms to give themselves sustenance and energy. They usually use some form of specialised digestive system to transform food into energy. They are motile, meaning that they can move and react to stimuli quickly and spontaneously. Animals are also multi-cellular organisms containing a complex mix of different cell structures featuring nuclei. Plants have some similar properties but lack the important characteristics such as being motile. They can move very slowly and react to stimuli over a long period of time but plants cannot respond straight away in the same way that animals can. Animals also have some form of intelligence that separates them from other things in nature. They have a brain and nervous system of some sort. This allows them to think, make decisions and react quickly to their external environment.
