Animals: Types, Habitats, Food Habits, and Interesting Facts

Animals are among the most vital organisms in the ecosystem. This is because they can be found all over the world ranging from forests, oceans, deserts, mountains, grasslands, rivers, as well as near homes. Some are big animals such as elephants and whales. Others are very small including ants and butterflies. They may be either solitary animals or live in herds. Animals can either be wild or domestic depending on their habitat. In all these cases, animals contribute a lot towards maintaining the equilibrium in nature.

At NatureNest, learning about animals is not only limited to knowing about their names and pictures. Rather, one should be able to learn more about their lifestyles, diet, habitat, and relevance. Animals play a big part in issues of biodiversity, wildlife, ecosystems, food chain, and conservation. One has to know about animals for proper comprehension of nature.

What Are Animals?

Animal organisms are the part of the animal kingdom. They are distinguished from plants by the inability of making their own food sources. They are heterotrophs since they are dependent on other living beings for energy sources. They are capable of moving around, breathing, growing, reproduction, and responding to changes in the environment.

Usually, animals are characterized by the presence of multiple cells, which is why they are considered to be multicellular organisms. They inhabit all areas of our planet except for those places where it is extremely cold. Some of the animals are terrestrial, others are aquatic, while some of them may exist in both types of habitats.

Animals also have diverse behavioral traits. Some of the animals are diurnal, while others are nocturnal. Some of the animals run fast, some of them swim fast, while others fly with ease.

Characteristics of Animals

There are some characteristics that animals possess in common.

First, animals are living organisms composed of several cells. Secondly, they require food for survival since unlike plants, they cannot make their own food. Thirdly, animals can usually move from place to place, even though such movements might be limited in nature.

One of the other characteristics of animals is that they grow and develop. An animal that has been born will not remain in its form forever but will become an adult organism. Another feature of the animals is reproduction, whereby animals reproduce by producing other members of the same species.

One of the other features is that animals react to the environment. When there is any sign of danger, the animal reacts either by running, hiding, flying away, or defending themselves. Another feature of the animals is the possession of a nervous system, which helps them to sense the environment.

Adaptation is one of the characteristics of animals. The adaptation refers to the development of some special features in the organism to help it survive in the environment.

Types of Animals

Animals can be divided into several major groups based on body structure and other biological features.

Mammals

Mammals are those kinds of animals which have hair and nurse their young ones with milk. The body temperature of mammals is generally steady because they are warm-blooded. Some of the mammals are lion, elephant, tiger, cow, dog, whale, and human beings.

Birds

Characteristics of a bird: Feathered creature having a beak, wings and two legs. Birds can fly, except for some species. They lay eggs and have warm blood. Some examples are peacocks, sparrows, parrots, eagles, owls and flamingoes.

Reptiles

Reptiles are animals with cold blood and scaled skin. Most of them lay eggs, and they mostly inhabit warm regions. Snakes, lizards, crocodiles, turtles, and tortoises are reptiles.

Amphibians

Amphibians can live both on land and in water. They usually start life in water and later move to land. Frogs, toads, and salamanders are examples of amphibians.

Fish

Fish live in water and breathe using gills. They have fins that help them swim. Fish are found in rivers, lakes, seas, and oceans. Tuna, goldfish, shark, and salmon are examples of fish.

Invertebrates

Invertebrates are animals without a backbone. They form the largest group of animals on Earth. Ants, butterflies, spiders, worms, octopuses, and jellyfish are all invertebrates.

Simple Classification Table

Type	Key Characteristics	Examples
Mammals	Fur or hair, feed babies milk	Lion, elephant, dog
Birds	Birds have feathers and wings	Peacock, eagle, parrot
Reptiles	Animals with scaly skin and are cold-blooded	Snake, crocodile, turtle
Amphibians	Animals living both on land and in water	Frog, salamander
Fish	Breathe through gills and live in water	Shark, salmon, tuna
Invertebrates	No backbone	Ant, butterfly, jellyfish

Animal Habitats

The habitat of an animal is the natural location where that animal resides. It provides food, water, shelter, and safety. The animals have different habitats as they adapt to their surroundings.

Forests

The forests provide homes for forest animals including tigers, elephants, deer, monkeys, foxes, and many kinds of birds. They give food, protection, and natural surroundings.

Deserts

Deserts are dry places and lack water. Camels, lizards, snakes, and some insects make their habitats in deserts where they can conserve water and avoid heat.

Grasslands

The grasslands consist of grass and trees in a small number. These include zebras, lions, antelopes, and bison.

Mountains

The mountain habitat is very cold and rocky in nature. Examples of animals that can live in such habitats include snow leopards, mountain goats, and yaks.

Oceans

The ocean habitat supports marine animals like whales, dolphins, sharks, fish, sea turtles, jellyfish, and coral reef animals.

Rivers and Wetlands

Animals supported by rivers and wetlands include fish, ducks, frogs, crocodiles, and insects.

Habitats are very significant as they provide animals with all necessities for their survival.

Food Habits of Animals

Animals have different food habits. These habits help classify them further.

Herbivores

The herbivore animals are those animals which consume plants in any form. The forms could be leaves, grass, fruits, seeds, or roots. Some examples are cows, deers, rabbits, giraffes, and elephants.

Carnivores

Animals which are meat-eaters and which hunt other animals for their consumption can be classified as carnivores. Examples of carnivores are lions, tigers, wolves, eagles, and sharks.

Omnivores

Animals that eat both plants and animals are called omnivores. Some omnivores are humans, bears, crows, and pigs.

Scavengers

Animals that eat the dead animals are called scavengers. Examples of scavengers are vultures, hyenas, and some insects.

Food habits are part of the food chain.

Interesting Animal Facts

Animals are full of surprises. Check out these interesting animal facts:

• Elephants have good memories and behave socially.
• Cheetahs run the fastest on land.
• Blue whales are the biggest living beings on earth.
• Owls rotate their necks much more than other birds.
• Ants can lift up objects many times heavier than themselves.
• Dolphins use sounds for communication.
• Camels can go without water for days.
• Frogs breathe using their skin.
• Some species of turtles live for more than a hundred years.
• Butterflies use their feet to taste food.

As you see, there are lots of interesting facts about animals.

Wild Animals VS Domestic Animals

Animals can be broadly classified into two categories, namely wild animals and domestic animals.

The first category consists of those that live in nature and have nothing to do with humans. These animals hunt and find food all by themselves. Examples include lions, tigers, bears, elephants, and deer.

The second category comprises those animals that either live with humans or depend on them for food and shelter. Examples include dogs, cats, cows, goats, horses, and chickens.

Comparison of Wild Animals & Domestic Animals Table

Feature	Wild Animals	Domestic Animals
Habitat	Forests, grasslands, seas, mountains	Houses, farms, settlements
Food	Source their own food	Often fed by humans
Behaviour	Independent lives	Lives in association with humans
Examples	Lions, tigers, deers	Dogs, cats, cows

Endangered Animals and Conservation

There are some animals that are endangered and this implies that there are animals that are on the verge of extinction. The reasons behind the disappearance of such animals are habitat loss, pollution, hunting, global warming and human activity.

Deforestation causes loss of home to animals that live in the forests, ocean pollution affects the aquatic life and when animals are poached then their population decreases very rapidly.

The examples of some endangered animals are tigers, rhinos, elephants, sea turtles and various birds and fishes.

Conservation involves:

• conservation of forests and wetlands
• establishment of wildlife sanctuaries and national parks
• elimination of poaching
• elimination of pollution
• tree plantation
• raising awareness regarding the protection of wildlife

Conservation is not an option; rather it is a necessity if we want future generations to witness animals in their natural habitats.

Why Are Animals Important for Nature?

Animals are not only pleasing to our eye. The balance of nature requires their presence.

Animals serve the purpose of pollination as well. Bees, butterflies, and even some birds transport pollen between plants thus ensuring the reproduction process.

Some species of animals disperse seeds. This way, birds and mammals bring seeds to different locations thus growing new forests.

Furthermore, animals take part in the food chain. Predators, preys, herbivores, and even scavengers are needed for the proper function of this chain.

Finally, biodiversity requires animals as well. Diversity of life on Earth consists of many species of different organisms including animals.

Besides, studying animals helps people in understanding diseases, human behavior, development, and changes in the environment.

In other words, animals are important to nature since it cannot function properly without them

Conclusion

Animals make nature diverse, balanced, and vibrant. Every animal, no matter how small or large, plays its own role in nature. There are animals that pollinate flowers; there are those that carry the seeds; there are those that make the environment clean; and there are those that maintain the food chain. This is why animals are very important for biodiversity and ecosystems.

In order to protect our planet in the future, we should protect animals and their habitats. Animal conservation is not just about one specific species. It is about the entire system of life.
