Introduction to the Animal Kingdom


Introduction to the Animal Kingdom

Animals are multicellular, eucalyptus-like organisms in the Kingdom Animalia. With few exceptions, animals breathe oxygen, eat organic matter, can move, reproduce sexually, and ingest other nutrients. Although animals derive most of their nourishment from a diet of organic matter, they obtain nearly all of their proteins, vitamins, minerals, and carbohydrates from what they can eat or snip off of other animals, plants, or even their own hair. They have a digestive system in which food is broken down into smaller components in order to allow them to be absorbed into their systems. Humans, chimps, dogs, cats, birds, and fish all possess some form of nervous system.

The major taxonomic classifications of animals are: Prototheria, being the nearest branch to the animal kingdom; Eutheria, which include all land animals; Metatheria, which include all marine animals; Classes A, B, and C, which include reptiles, amphibians, and mollusks; Classes D and E, which include fishes, amphibians, mammals, and birds; and Class C, which includes ants, crustaceans, and alligators. Virtually all mammals are warm-blooded and require an environment with a warm temperature and high humidity to survive. Land animals, which derive their nourishment from the air and water, belong to the class of eutorobi, while the saurian and cetacean suborder is considered the subkingdom.

Most animals have both a mouth and a nose, but there are some exceptions, as does the octopus. Only a few animals have both a mouth and a nose, which are the dinosaurs. Each animal has specialized sensory organs such as the sense of taste and the sense of smell, which are present in all its parts except for the eyes, head, hind limbs, tail, and few digits on its toes. The remainder of the animal’s body is covered with a thick hard exoskeleton, which serves as the recipient of the nerves and other communications carried by the brain.

Within the class of mammals, we have the four basic classes, namely the metathesis, the metronomes, the bicuspids, and the eutherians. Among these animal classes, the most famous are the amphibians and reptiles. Most amphibians and reptiles belong to the class of plastids, while mammals generally belong to the class of reptile. Among reptile and mammal families, the orders reptiles and reptopridae contain the common reptiles and the true dinosaurs, respectively.

People are familiar with different animal types and many of them are widely used in daily life, including pets, fashion trends, science, medicine, etc. There are many species of plants, including fruits, vegetables, and even flowers. Insects are important components of our ecosystem as they help in digestion of plant foods and spread disease. Fish, birds, mammals, and reptile varieties are some of the animals that serve different functions in our ecosystem. Many of the animals that we do not even recognize can be found within the class of mammals and amphibians.

Within the class of animals, there are two basic classifications, the Kingdom of Animals and the Phylum of Animals. The Kingdom of Animals contains all the animals that are part of the phylum, while the Phylum of Animals includes all the terrestrial animals and all the ocean-dwelling animals. whales, dolphins, trilobites, manta rays, walnut frigate birds, sperm whales, blue whales, hippos, and crocodiles are examples of the classifications of animal species. Cephalopods, cephalopod legs, and leptocudos, snails, and slugs also belong to the class of animal species. In short, the animal kingdom consists of a great number of different animal species and each serves a specific purpose in the ecosystem.
