Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration.\n\nFunction\nIn mammals\nIn most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.\n\nAs an interface between the body and the external world, the nose and associated structures frequently perform additional functions concerned with conditioning entering air (for instance, by warming and/or humidifying it) and by mostly reclaiming moisture from the air before it is exhaled (as occurs most efficiently in camels).\n\nIn most mammals, the nose is the primary organ for smelling. As the animal sniffs, the air flows through the nose and over structures called turbinates in the nasal cavity. The turbulence caused by this disruption slows the air and directs it toward the olfactory epithelium. At the surface of the olfactory epithelium, odor molecules carried by the air contact olfactory receptor neurons which transduce the features of the molecule into electrical impulses in the brain.\n\nIn cetaceans, the nose has been reduced to the nostrils, which have migrated to the top of the head, producing a more streamlined body shape and the ability to breathe while mostly submerged. Conversely, the elephant's nose has become elaborated into a long, muscular, manipulative organ called the trunk.\n\nHuman nose\nThe visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils.\n\nYou could get more information from the link below...

They are not particularly closely related, but they are both in the order Rodentia.  They probably split somewhere between 65-55 million years ago (though some genetic studies suggest it could be much older).\n\nThey share characteristics of rodents: evergrowing incisors, 1 top incisor and 1 bottom incisor (per side).  They have no canines, the maxilla is a part of the zygomatic arch.  There are additional physical characteristics as well as genetic ones.

i think animalia contains all animals - fish, reptiles, mammals, birds and amphibians. dolphins are obviously not bacteria, fungi, insects, etc. if you meant mammalia it is because dolphins -\nbreathe air with lungs, not gills\nbreastfeed their young that do not hatch from eggs\nhave four chambered hearts

The mammals are the class of vertebrate animals characterized by the presence of mammary glands, which in females produce milk for the nourishment of young; the presence of hair or fur; and endothermic or "warm-blooded" bodies. The brain regulates endothermic and circulatory systems, including a four-chambered heart. Mammals encompass some 5,500 species, distributed in about 1,200 genera, 152 families and up to 46 orders, though this varies with the classification scheme.\n\nPhylogenetically, Mammalia is defined as all descendants of the most recent common ancestor of monotremes (e.g., echidnas and platypuses) and therian mammals (marsupials and placentals).

Animals are a major group of organisms, classified as the kingdom Animalia or Meta­zoa. In general they are multi­cellular, capable of locomotion, responsive to their environment, and feed by consuming other organisms. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on.\n\nThe word "animal" comes from the Latin word animal, of which animalia is the plural, and ultimately from anima, meaning vital breath or soul.\n\nCharacteristics\nAnimals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular, which separates them from bacteria and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls.\n\n\nStructure\nWith a few exceptions, most notably the sponges (Phylum Porifera), animals have bodies differen­tiated into separate tissues. These include muscles, which are able to contract and control locomotion, and a nervous system, which sends and processes signals. There is also typically an internal digestive chamber, with one or two openings. Animals with this sort of organization are called metazoans, or eumetazoans when the former is used for animals in general.\n\nAll animals have eukaryotic cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules. During development it forms a relatively flexible framework upon which cells can move about and be reorganized, making complex structures possible. In contrast, other multicellular organisms like plants and fungi have cells held in place by cell walls, and so develop by progressive growth. Also, unique to animal cells are the following intercellular junctions: tight junctions, gap junctions, and desmosomes.\n\nReproduction and development\nNearly all animals undergo some form of sexual reproduction. Adults are diploid or polyploid. They have a few specialized reproductive cells, which undergo meiosis to produce smaller motile spermatozoa or larger non-motile ova. These fuse to form zygotes, which develop into new individuals.\n\nMany animals are also capable of asexual reproduction. This may take place through parthenogenesis, where fertile eggs are produced without mating, or in some cases through fragmentation.\n\nA zygote initially develops into a hollow sphere, called a blastula, which undergoes rearrangement and differentiation. In sponges, blastula larvae swim to a new location and develop into a new sponge. In most other groups, the blastula undergoes more complicated rearrangement. It first invaginates to form a gastrula with a digestive chamber, and two separate germ layers - an external ectoderm and an internal endoderm. In most cases, a mesoderm also develops between them. These germ layers then differentiate to form tissues and organs.\n\nAnimals grow by indirectly using the energy of sunlight. Plants use this energy to convert sunlight into simple sugars using a process known as photosynthesis. Starting with the molecules Carbon Dioxide (CO2) and Water (H2O), photosynthesis converts the energy of sunlight into chemical energy stored in the bonds of Glucose (C6H12O6) and releases Oxygen (O2). These sugars are then used as the building blocks which allow the plant to grow. When animals eat these plants (or eat other animals which have eaten plants), the sugars produced by the plant are used by the animal. They are either used directly to help the animal grow, or broken down, releasing stored solar energy, and giving the animal the energy required for motion. This process is known as glycolysis.\n\n\nOrigin and fossil record\nAnimals are generally considered to have evolved from flagellate protozoa. Their closest living relativ

It squats, it pushes, out it comes. Much like a dog, I would imagine (except for their being no grass to wipe its feet).\n\nI can't think how it would be any different from any other mammal...

Basically all mammals are genetically similar to humans. But some more so than others like dolphins and the great apes, i.e. Chimpanzees and gorillas of which we are 98% genetically identical.

General Characteristics\nTaxonomy is the science of classification of organisms. Primates are difficult to classify. Most scientists classify primates, monkeys, and apes in the Kingdom Animalia, the Phylum Chordata (animals with a supporting rod along the back, this also includes sharks and rays), Subphylum Vertebrata (animals with a bony backbone), the Class Mammalia, and the Order Primates. As of 2004, there are 363 species of primates. In addition to monkeys and apes, the order includes prosimians ("premonkeys") such as lemurs and bushbabies as well as humans.\n\nAs mammals, primates possess the mammalian characteristics of endothermy (internal regulation of body temperature, often known as warm-bloodedness), bearing live young (placental), and feeding their young with milk produced by mammary glands. \n\nNot all primates possess the same characteristics—there is no unique characteristic that defines a primate. Most shared characteristics and trends are not derived but instead are a retention of ancestral features, which also adds difficulty to classifying primates. Many of these characteristics are behavioral, or depend on soft tissue anatomy; this does not help in identifying fossil primates. This retention of a fairly generalized body type, unlike hoof stock for example, reflects their diversity of life style. Their unspecialized morphology and highly flexible behavior allows them to fill many niches and adapt to environmental change.\n\nThere is a number of rather specific primate characteristics, such as details of the bones of the foot and skull. However, these characteristics do not make it easy for scientists to categorize early mammals and primates. There are a few scientists who consider tree shrews primates and bats the closest living relative to primates.\n\nSome distinguishing characteristics of primates include:\n\nForward-facing eyes for binocular vision (allowing depth perception) \nIncreased reliance on vision: reduced noses, snouts (smaller, flattened), loss of vibrissae (whiskers), and relatively small, hairless ears \nColor vision \nOpposable thumbs for power grip (holding on) and precision grip (picking up small objects) \nGrasping fingers aid in power grip \nFlattened nails for fingertip protection, development of very sensitive tactile pads on digits \nPrimitive limb structure, one upper limb bone, two lower limb bones, many mammalian orders have lost various bones, especially fusing of the two lower limb bones \nGeneralist teeth for an opportunistic, omnivorous diet; loss of some primitive mammalian dentition, humans have lost two premolars \nProgressive expansion and elaboration of the brain, especially of the cerebral cortex \nGreater facial mobility and vocal repertoire \nProgressive and increasingly efficient development of gestational processes \nProlongation of postnatal life periods \nReduced litter size—usually just one (allowing mobility with clinging young and more individual attention to young) \nMost primates have one pair of mammae in the chest \nComplicated social organization
