Animals are multicellular, living organisms in the animal kingdom. Although they may be classified as animals because of their ability to move and breathe, they are really protozoa, a class of mollusk and even an archoskeleton of some turtles and snakes. Most animals are carnivores, although there are many omnivores. With few exceptions, all animals breathe air, eat organic matter, can move, reproduce sexually, and have the nerve endings that allow them to feel pain. Humans, however, have both a mouth and a nose.
All animals belong to the Kingdom Animalia, the most inclusive of all animal kingdoms. The other five animal kingdoms are Eutheria (fish), Protista (males and females), Subclassia (reptiles and amphibians) and Classida (males and females). All animals are composed of several classifications or classes. In comparison to humans, all other animals have more than one class. Humans, for instance, have ten classes, although all other animals have more than one.
The classification of animal is based on the arrangement of its body systems and its physiology, which include the arrangement of its limbs and its organs and the arrangement of its skin and its digestive tract, even though the analysis of animal anatomy is difficult. The arrangement of the animal body and its arrangement of the internal parts of the animal to determine the organisation of the animal. Each animal has twelve different organs, but in most cases only six of the organs constitute an animal. Furthermore, all animals have sensory organs, which are set into the skin or into a cavity within the skin, or into a bony labyrinth connected to the head. Animal senses include taste, smell, touch, and hearing.
Animal species is a species that lives and dies independently of other species. There are three categories of animals: the Prototheria, the Metatheria, and the Eonura. The Prototheria include the alligator, iguana, alligator-necked lizards, allostery, butterfly, crab, and the monitor lizards. The Metatheria are trilobites and molluscs, with the exception of hippos, which belong to the Metatheria.
The invertebrate or “non-vertebrate” animals are classified as having an animal form that needs no external aid to survive. These include such diverse species as insects, crustaceans, arthropods, salamanders, slugs, snails, and some fishes. In contrast, molluscs and some fishes are classified as having a hard external shell to protect them from predators. The classification of an animal species is often affected by similarities and differences between species, especially in terms of appearance and habits, but the relation between animals is often not considered when assigning a taxonomic rank to any one species.
The Cymilidae and Diogenidae are two broad classifications of insects, with the former referring to wingless, water-dwelling, aquatic insects, and the latter to terrestrial insects, with some genera having wings capable of flight. The Cymilididae include all butterflies and insects with elongated wings, whereas the Diogenidae have wings which are short and tapering. The representatives of the Cymilidae include such familiar garden plants as ladybirdlilies, gardenia, cicada, houseplant, sugar glider, spider mite, and many others. Some representative members of the Diogenidae are chinchillas, ants, and several species of millipedes.
Insect classification and relationships | animals | animal | animals make great | forms} All the forms of insects discussed above are alive, so it is often difficult to classify them into classes or orders. But the general idea is that animals make great pets because they are so similar to us. They are capable of traveling with us, eating foods we eat and taking care of many of our basic needs. They have hearts as well as lives, minds as well as bodies.
