1. The Animalia Kingdom It is one of the five high-hierarchy scientific classifications of living beings, in which cases they acquire the name of kingdoms. This category includes all organisms that have the same set of basic characteristics -eukaryotic, multicellular, and heterotrophic- corresponding to animals. Also, it can be called Animal Kingdom or metazoan.
Etymology: Kingdom, from Latin regnum.+ Animalia, from Latin animaliaplural form that corresponds to the modes animal, animalis.
Grammatical category: masculine noun
in syllables: rei-no + a-ni-ma-lia.
Animalia Kingdom
The name of Kingdom Animalia is the one that is used to name the kingdom made up of animals and that is, without a doubt, the best known by human beings (who are also part of it).
Kingdom that integrates vertebrate and invertebrate animals and among them the human species. Main features
The animal kingdom is characterized by having members that manage to develop their own mobility, unlike what happens with the members of the kingdom of plants or fungi. Animals appear on planet Earth in a very important diversity, having thousands of species but also differentiation based on the type of cells that compose them, the type of diet they develop, etc.
Unlike what happens, for example, with the Monera kingdom, made up mainly of unicellular organisms (that is, with a single cell), the Animalia kingdom is made up of multicellular organisms, which means that its organic structure is much more complex and, depending on the type of animal and its species, the physical appearance will be much more complex as well.
At the same time, this variety of cells found in the formation of animals is what allows the existence of so many variants in terms of size, color, type of hair or skin, way of feeding, etc. Animals, unlike bacteria, are eukaryotic organisms, which means that in all their cells there is a well-defined nucleus, which contains the specific genetic material for each specimen.
Another very important characteristic in the animal kingdom, which differentiates these living beings from fungi and plants, is that all its members are heterotrophs. In other words, being heterotrophic means that food must be sought outside of their organism since they cannot produce it themselves (as plants do). In addition, they also all consume oxygen, to a greater or lesser extent.
Finally, animals have a process of existence that is characterized by reproduction and development, at which time the organism slowly acquires those typical characteristics of its species and that will give it its final physiognomy.
Within the animal kingdom, two subgroups can be distinguished, vertebrates and invertebrates, each with its own particular characteristics.
The first group includes all those who have a vertebral column in its organic conformation, while the second group includes those who lack it.
In humans, the vertebral column or backbone is a highly complex, articulated and resistant structure that is shaped like a longitudinal stem. It is located in the middle and posterior part of the trunk and extends from the head to which it supports, and passes through the neck and back until it reaches the pelvis, part of the human body to which it supports.
The discs, vertebrae, and spinal cord are the building blocks of the spine.
It acts as a communication conduit with the brain, carrying and bringing the corresponding signals through the spinal cord.
For example, a lesion in the latter produces a certain and serious failure in the exchange of information to relevant parts of the body such as the legs and arms, which allow the mobilization of the human being and also that they can reach or take things.
Differential features of human beings with respect to other members of the animal kingdom
Meanwhile, human beings belong to the animalia kingdom, who are of this group the most developed species in intellectual matters, since we are the only ones with the ability to reason.
The mental capacities that human beings possess and that are absolutely typical of this species allow them to think, invent, learn abstract concepts and use linguistic structures of enormous complexity, issues that the rest of the animal kingdom cannot do, because they have limited or non-existent capacities. in this sense.
We must also say in relation to displacement and movement, that human beings are undoubtedly the ones that show the most plasticity in this sense within this group, since we can carry out a wide range of movements that makes us capable of dancing, playing sports, and many other daily activities that other animals cannot perform.
On the other hand we have the ability to manipulate and manufacture elements by our opposable thumbs.
