Animals By Conservation Status
- A multi-cellular constitution, which means that the structure of every member of animal kingdom is formed by more than one cell, independently from the sub-kingdom. This feature differences animals from protozoa which are unicellular organisms.
- Every animal presents on its structure eukaryotic cells which are cells with a real core which contains the deoxyribonucleic acid (DNA) which constitutes the genetic information of the animal.
- An animal cell does not have a cellular wall, these cells are separated from their environment by just a membrane, and therefore they are more flexible than vegetable cells which indeed have walls.
- The bodies of the animals present differenced tissues except sponges. Plants also present differenced tissues, but the tissues of animals are characteristic, among them we can find the nervous tissue which allows the flow of electric impulses and the muscles which allow the movement and locomotion.
- All the animals are capable of voluntarily moving from one place to another at any stage of their lives. Those animals that have to spend their adult lives on a fixed place like corals are capable of moving from one place to another pm pre-adult stages, for instance, when they are on a larval stage. Movement capacity is a direct consequence of the structure of members of animal kingdom, the presence of muscle and nervous tissue is what allows the movement on animals.
- Animals have an internal or external skeleton which provides support for the body and internal organs. In the case of vertebrate animals, they have an internal skeleton and it is formed by bones. In the case of invertebrate animals, the skeleton can be external (exoskeleton) which is mainly formed by chitin, they can also have internal hydrostatic skeleton which is formed by pressurized fluid that is present on mollusks, worms and nematodes.
- All the animals have an internal digestive tract; therefore they are feed by the ingestion of foods which are processed by the digestive system to nourish the organism. Animals also discard the waste left by food processing after digestion.
- These individuals present precise limits except corals; they are clearly separated from their environment and from other individuals of the same species.
- Animals present two different genres and they sexually reproduce however there are some species which can also asexually reproduce. The reproduction takes place when the sperm of the male member fertilizes the ovule of the female member.
- Most of animals are Heterotrophs, it means that they are unable to produce their food therefore they should be fed by other organism in order to survive.
Due to the great amount of threats which affect species present on our planet, it was necessary to make an evaluation of the vulnerability of these species in order to promote diverse conservation initiatives and plans for species protection. There are many species in danger of extinction and the governments of every country are working to promote the preservation of these species, some of these species include the Imperial Iberian Eagle, Sea Turtle, Giant Panda, African Black Rhino, Whale and the Grizzly Bear among others.
Our list of animals
For those of you willing to discover everything about all the animals of the world, we will try through this website to introduce you in the fantastic world of animals, to learn more things about their habitat and their way of living. You will find this site a very easy way to find all the animals of the world, classified in as many categories as you need just in order to bring into your lives the pure joy of nature.
We have created this list of animals for you and we hope you will enjoy browsing through our pages about different species. To make it easier for you, this list of animals is divided using three main criteria such as carnivore, herbivore and omnivore.
For all of you who wants to learn more about some of the special species, we gathered the information in categories named Threatened, Endangered, Vulnerable and Extinct. This way you’ll be able to find out much more about all the animals in the world which are in danger.
Even if some species of animals are just threatened to disappear or they’re just very vulnerable, our team managed to bring all the information you need in order to know all the important things about our world of animals.
Think about it just for a second. From now on, the answer for all you need to do in order to find the right piece of information about your favourite animals is right here. You just have to thoroughly browse our site and read all the articles you like. And enjoy them.
To make it even easier for you, we’ll start a list of animals classed as reptiles, followed by fishes, birds and mammals.
Reptiles are often labeled as aggressive and dangerous animals, that makes your blood "freeze". Below, we will see that, in fact, they are extremely captivating animals that deserve more understanding on our part.
There are about eight thousand species of reptiles, living on almost every continent of the world. They do not live in Antarctica, where it is too cold. They have shown on our planet about 200 million years ago, long before mankind.
The term "cold-blooded" is not exactly true. Reptiles are poikilothermic, meaning they regulate their body temperature using external sources. Their body is not able to control the internal temperature as it happens with mammals.
Reptile brain represents only 1% of body mass and their jaws are so conformed that they can not chew. Reptiles are forced to swallow their whole prey. Most reptiles lay eggs. There are some species that give birth to living pups (boa constrictor is one of them).
Our list of animals continue with fishes, which are vertebrate animals which lives in the aquatic environment. The fish breathes oxygen dissolved in water. We know almost 30000 species of fish. The science that deals with the study of fishes is called ichthyology. Fishes are the least developed of the vertebrates from the list of animals.
The body of a fish has a hydrodynamic and fusiform shape, and it can be dorso-ventrally flattened, consisting of three parts: head, trunk and tail. A fish has two types of fins: paired (pectoral and abdominal) and unpaired (dorsal, tail and anal). The paired one have a stable structure, being composed of parts of girdle and pelvic bone. They help the fish to dive into the water, to make revolutions and even to keep the body in a normal position.
The unpaired are folds of skin supported by bony rays. Tail fin is the part of the fish that propels it forward, participating in maintaining equilibrium during swimming. The skin is covered with a skin glandular mucus secreted by the cells. The body is covered with protective scales or plates of dermal bone.
Birds are other animals present in our lives and in our list of animals. Unlike our four-legged friends, the birds are more sensitive in terms of food and conditions they live. Each specie has certain standards of life and the health of birds is strictly related to these issues. The health of birds is indicated primarily by the behavior and appearance of the animal.
Mammals are included, too, in our list of animals, being the most advanced and adaptable vertebrates on Earth. More closely related to man, mammals are found on all continents, in all oceans and the oceanic islands of the world.
Mammals are typically characterized by their highly differentiated teeth. Teeth are being replaced just one time during the life of mammals. Other features found in most mammals are the jaw consisting of one bone, the heart having four chambers, the palate separating the mouth from the digestive tract airways, the brain being highly developed, constant body temperature being internally regulated, separate sexes and sex of an embryo being determined by the presence of XX chromosomes in females and XY in males and fertilization occuring internally.
Often, groups of mammals are differentiated after skull characteristics.
There are 3 major groups of mammals presented in this list of animals, each based on a common characteristic embryo from each species group. Monotremes lay eggs, and this method of reproduction is most common in primitive mammals. Marsupials (kangaroo, koala) give birth to underdeveloped puppies after a very short incubation period (between 8 and 43 days). Pups are born in a relatively early stage of morphological development. They attach to their mother‘s nipple where they spend a period of time proportional to develop to compensate low during gestation. Immediately after birth, the babies of mammals are highly dependent on milk. Apart from these generalities, mammals show a high behavioral diversity.
Our list of animals classifies them in carnivorous, herbivores and omnivores.
Carnivorous animals of the family Canidae are valued mostly for their great strength and adaptability in the wild they live, but also in opportunistic behavior to seek prey. The category of these animals include dogs, jackals, wolves, foxes and coyotes. Such mammals have slender body, unretractable claws, sharp nose and bushy tail. Body construction is specific to animals that have the ability to run fast and stay on their feet for a long time. An advantage of these animals in the battle for survival is that they have well-developed senses, such as an excellent visual acuity and a highly developed smell and hearing.
Herbivores (such as bisons, rabbits, horses, sheep, goats, deer, giraffes) are endowed by nature for feeding exclusively on leaves and grass. Granivores (birds) thrive on seeds of various plants. Carnivores feed on raw meat, but no, they can not thrive on a diet based exclusively on meat. Frugivores (monkeys) are feeding on fruits, vegetables, roots, buds, nuts and seeds.
Omnivores are those animals who are feeding with plant and animal substances. That means they are the only ones from the list of animals that eat all kind of things. Omnivorous mammals have teeth differentiated to a mixed regime, poorly developed canines, incisors are more stretched and molar tooth are blunt. These mammals can feed both food animal and vegetable nature, especially fruits. These include wild boar, hippopotamus, brown bear and the white bear.
On the other hand, omnivorous birds usually feed during the summer with worms, larvae, insects, while the autumn and winter, early spring and in summer, some of them eat fruits and seeds of herbaceous plants and various shrubs. Omnivorous fish feed on aquatic plants and animals derived from lesser water (insect larvae, crustaceans, etc.).
This is our list of animals and we hope you enjoy reading it and all other related posts.
