These animals, due to lack of appendages, use their bodies to generate propulsive force. These movements are sometimes referred to as "slithering" or "crawling", although neither are formally used in the scientific literature and the latter term is also used for some animals moving on all four limbs.
Animals have been hunted and farmed for their fur to make items such as coats and hats. [173] Dyestuffs including carmine , [174] [175] shellac, [176] [177] and kermes [178] [179] have been made from the bodies of insects. Working animals including cattle and horses have been used for work and transport from the first days of agriculture. [180]
Birds also have specialized structures called air sacs closely associated with their lungs that store air when the animal inspires, further reducing body weight and maintaining the partial pressure of oxygen within the lungs equal to that of the surrounding environment. While highly beneficial for flight, decreasing body weight (and thus whole ...

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
Animals serve as models in biological research, such as in genetics, and in drug testing. Many species are kept as pets, the most popular being mammals, especially dogs and cats. These are often anthropomorphised. Animals such as horses and deer are among the earliest subjects of art, being found in the Upper Paleolithic cave paintings such as ...
Segmentation in biology is the division of some animal and plant body plans into a linear series of repetitive segments that may or may not be interconnected to each other. This article focuses on the segmentation of animal body plans, specifically using the examples of the taxa Arthropoda, Chordata, and Annelida. These three groups form ...
The goat is a terrestrial animal.. Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians).
There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by no means be considered complete and authoritative and should be used carefully.
