What Is An Animal?

An animal is a living organism that belongs to the kingdom Animalia, one of the major groups of living things. Animals are multicellular eukaryotic organisms that are distinguished from plants, fungi, and bacteria by their ability to move, consume food, and reproduce sexually.

Animals come in a wide variety of shapes and sizes, from tiny microscopic creatures to large and complex beings like elephants and whales. They also exhibit a wide range of behaviors and adaptations that allow them to survive and thrive in various environments.

Some animals are domesticated and kept as pets or used for various purposes by humans, while others live in the wild and play important ecological roles in their ecosystems. Here we have compiled a complete list of animals a-z with pictures, videos, facts, news, and more.

What Are the Two Major Groups of Animals?


They are animals without a backbone or spinal column. They make up the vast majority of animal species and include insects, crustaceans, mollusks, worms, and many others.


Vertebrates, on the other hand, are animals with a backbone or spinal column such as fish, amphibians, reptiles, birds, and mammals. Vertebrates are typically more complex and specialized than invertebrates, with more developed nervous, respiratory, and circulatory systems.

When Did Animals First Appear?

The earliest animals come from fossils that date back more than 600 million years ago, during a period of time known as the Ediacaran or Vendian period. These fossils show impressions of soft-bodied creatures that lived in the oceans and may have resembled simple jellyfish, sponges, or worms.

What Are the Basic Functional Systems Of Animals?

Animals have several basic functional systems that enable them to survive and thrive in their environments. These systems include:

Nervous System

The nervous system coordinates and controls the body’s responses to internal and external stimuli such as the brain, spinal cord, and nerves.

Circulatory System

The circulatory system is responsible for transporting oxygen, nutrients, and other vital substances throughout the body such as the heart, blood vessels, and blood.

Respiratory System

The respiratory system enables animals to exchange gases with the environment, taking in oxygen and releasing carbon dioxide. It includes the lungs and other respiratory structures.

Digestive System

The digestive system breaks down food and absorbs nutrients while eliminating waste products. It includes the mouth, esophagus, stomach, intestines, and associated organs.

Musculoskeletal System

The musculoskeletal system provides support, movement, and protection for the body such as bones, muscles, tendons, and ligaments.

Reproductive System

The reproductive system enables animals to produce offspring, ensuring the continuation of their species. It includes the reproductive organs and associated structures.

How Are Animals Different From Plants And Fungi?

Animals are different from plants and fungi in several ways including Cellular Structure, Mode of Nutrition, Mobility, Reproduction, and Habitat.

Are Insects Animals?

Yes, insects are animals. More specifically, insects are a type of invertebrate animal that belong to the phylum Arthropoda, which also includes crustaceans, spiders, and centipedes, among others.
