The animal kingdom if full of every animal you can think of, because the animal kingdom all animals are a part of it. Also all animals are multicellular and heterotrophs. Animal cells lack the rigid cell walls that characterize plant cells. The bodies of most animals (all except sponges) are made up of cells organized into tissues, each tissue specialized to some degree to perform specific functions. In most, tissues are organized into even more specialized organs. Most animals are capable of complex and relatively rapid movement compared to plants and other organisms. Most reproduce sexually, by means of differentiated eggs and sperm. Most animals are diploid, meaning that the cells of adults contain two copies of the genetic material. The development of most animals is characterized by distinctive stages, including a zygote, formed by the product of the first few division of cells following fertilization; a blastula, which is a hollow ball of cells formed by the developing zygote; and a gastrula, which is formed when the blastula folds in on itself to form a double-walled structure with an opening to the outside, the blastopore. Somewhere around 9 or 10 million species of animals inhabit the earth; the exact number is not known and even our estimates are very rough =====

Mollusks: Molluscs have for many centuries been the source of important luxury goods, notably peals, mother of peal, Tyrian purple dye, and sea silk. Their shells have also been used as money in some pre-industrial societies. Some molluscs contain toxic compounds. Mollusks were among the first inhabitants of the Earth. Fossils of mollusks have been found in rocks and date back over 500 million years. Mollusk fossils are usually well preserved because of their hard shell.

Anthoprods: Arthropods range in distribution from the deep sea to mountain peaks, in size from the king crab with its 12-foot armspan to microscopic insects and crustaceans, and in taste from chocolate covered ants to crawfish jambalaya and lobster Newburg. Despite this unbelievable diversity, the basic body plan of arthropods is fairly constant. Arthropods have a stiff cuticle made largely of **chitin** and proteins, forming an exoskeleton that may or may not be further stiffened with calcium carbonate.

Echinoderm: Echinoderms have tentacle-like structures called tube feet with suction pads situated at their extremities. These tube feet are hydraulically controlled by a remarkable vascular system. Reproduction is carried out by the release of sperm and eggs into the water. Most species produce pelagic. Echinoderms are protected through their spiny skins and spines. But they are still preyed upon by shells (like the triton shell), some fish (like the trigger fish), crabs and shrimps and by other echinoderms like starfish which are carnivorous. Many echinoderms only show themselves at night (= nocturnal), therefore reducing the threat from the day time predators. ea stars are characterized by radial symmetry, several arms (5 or multiplied by 5) radiating from a central body. Mouth and anus are close together on the underside, the anus is at the center of the disc together with the water intake (madreporite). The upper surface is often very colorful.

Axes: Axis Deer, also known as Chital Deer or Spotted Deer, is the native animal of the Indian subcontinent. It is found very commonly in India and is one of the most beautiful animals in the country. The spotted deer of India was introduced in the state of Texas in the 1930s. Since that time, it has become the most widespread of the entire deer species. Chital deer are found mostly in large family units, where a doe remains with her mother even after becoming a mother herself. Spotted deer can be seen roaming around either in mixed groups or separate bachelor groups.
