I wrote this article rather by accident, really. It all begun when my husband and I owned an exotic pet store and we were faced with the task of quickly educating our clients (and their children) when it comes to animals and wildlife. Well, there is no way to write up a quick little list of the animal kingdom! Hence, this article soon became an important share of a labor of love and flourished into a life of it is own. The world of animal study is a finelooking one. Unfortunately, so numerous of our animal species are getting endangered or tardily going extinct. It is for this reason we offer this selective information for study. It is so important, particularly for our young persons to perceive the kinship amongst man and animals.

The Animal Kingdom:

Today, nearly million types of animals have been came across on the Earth, and a lot of more will hopefully be encountered as people proceed to explore the forests, the seas and the galore other habitats on our planet.

Animals form one of the two great kingdoms of the living world; the other form is plant life. There is tremendous potpourri of animal life, ranging from the microscopic protozoan, to the gigantic blue whale, measuring over 100 feet long, and over 100 tons in weight!

One of the biggest divergences amid plant and animal life is in the method of feeding, and obtaining energy. Unlike green plants, animals can not make their own food. They have to take in ready-made feed in the form of other animal or plant matter. Such feed has to be found, and therefore, most animals are competent to move around freely to accommodate their needs. In addition, animals have nervous systems to control their movements, and sensory organs to help them to find the suitable feed they need.

These features in general distinguish more spectacular animals from plant life, but there are still a number of microscopic organisms that defy a firm classification. These include free-swimming creatures with sensible eyespots, which once in a while feed like plants. They do this by taking in water and carbon dioxide and combining them to form sugars. They may also take in feed like animals do, as well. Zoologists classify these creatures as “animals,” yet a great deal of botanists consider them to be algae. Still others consider them to be a portion of a discerned kingdom known as the Protista. However we classify these difficult organisms, we may be reasonably sure it was through creatures like these that both the animal and plant kingdoms arose galore two billion years ago!

Classifying Animals:

Zoologists have divided the animal kingdom into with regards to 30 major groups called Phyla. The members of each Phylum part the same basic structure and organization, even though they may look very different. Fish, birds, and humans, for example, all belong to one phylum known as the Chordata, because all of these living species have backbones. Yet, their external appearances are wholly different.

The phyla are disunited up into a number of classes, whose members have much more in common. All the birds, for example, are warm-blooded, feathered, egg-laying creatures, and all are placed in the class Aves.

Classes are separated into Orders, and those members have even more in mutual with each other. For example, the Falconiformes order holds hawks and eagles, and their relatives; all day-flying birds of prey with sharp talons and hooked beaks.

Within each order, there are ordinarily a number of Families, each of which holds very almost affiliated animals. In the animal kingdom, a family name always ends in the letters -i-d-a-e (-idae).

Within each family, there are one or more Genera (singular: Genus), whose members are even more closely affiliated and often times very similar. For example, the Buzzard and the Rough-legged Buzzard are very much alike, and both are members of the genus Buteo. Each distinct animal species has a scientific name made up of the name of it is genus and a specific name. For example, the Rough-legged Buzzard is known as Buteo lagopus, while the Buzzard is Buteo buteo. These scientific names, which are normally printed in italics, are understood by zoologists all over the world.

The members of each animal species integrate the blueprint for that species, within the cells of their bodies. Because they commonly mate only with their own kind, they mechanically give rise to more of the same kind when they breed. Animals aren’t ordinarily attracted to other species for mating, primarily because they don’t give the right “signals” to one another. In addition, mating amongst dissimilar species is many times times physically impossible, even if they were to meet. Closely affiliated species may now and then mate in captivity, and the procedure is successful, the animals will manufacture offspring known as hybrids. The best known example is the Mule, resulting from the mating of a Male Ass (no insult intended to anyone!) or Donkey and a female horse. However, hybrids are in general sterile, accordingly unable to construct further offspring. That way, the species do not become mixed up.

With or Without Backbones:

One ordinarily used method of classifying animals into the animal kingdom is to divide it into animal species with backbones (vertebrates) and animals without backbones (invertebrates). This is rather a utile method, exceptionally for study and instructing purposes, but it is a very unequal division. There are invertebrate animals in all the phyla, but the vertebrates belong to just one portion of one phylum, the Chordata.

The vertebrates include the largest, more usual animals like cats, dogs, horses, cows, and birds. Yet they likewise include most fish, and almost all amphibians, and reptiles. The invertebrates group include worms, slugs, snails, insects, spiders, and galore others. But don’t think that all the vertebrates are big and all the invertebrates small! There are larges invertebrates such as giant squid, which are a portion of the genus Architeuthis. Their bodies are around 16 feet long, with tentacles three times this length, and they may weigh up to two tons! Compare these figures with those for the smallest vertebrate, the Dwarf Goby. This tiny little fish from the Philippines measures only half an inch long. One of the smallest mammals, known as the Etruscan Shrew, has a body that is only 2 inches long! It is a good deal littler than galore insects.

We live in a magnificient world of science and beauty. The Animal Kingdom is a vast key to our own humane existence. It is always in motion – growing and altering with each and each passing day.
