The Structured Way We Organize All Animals

Did you know that the animal kingdom holds a huge number of living things? Scientists sort animals into groups to better grasp how they relate to one another, what makes them unique, and how they evolved over time. Animals are organisms with many cells and complex cell structures. They go from simple sponges to complex mammals. Scientists place them into various large sections, smaller sections, even smaller sections, and so on, based on shared traits and family history written in their genes.

How Do We Sort All The Animals?

The process of sorting animals is not random. It follows a hierarchy, a system that goes from very large groups to very specific individuals.

What Are The Biggest Groups of Animals?

At the highest level, scientists place animals into major large sections called phyla. These phyla show very basic body plans and biological features. Examples of major phyla are:

• Chordata - This group includes animals with backbones, such as mammals, birds, reptiles, amphibians, as well as fish.
• Arthropoda - Insects and crustaceans belong here.
• Mollusca - Snails and squids are examples.
• Annelida - These are worms with body segments.
• Porifera - Sponges belong to this group.
• Cnidaria - Jellyfish and corals are in this section.
• Echinodermata - Starfish and sea urchins are examples.

How Do We Sort Animals Within Those Groups?

Within these large phyla, scientists sort animals further into classes and orders. A good illustration:

• The class Reptilia holds orders like:
• Crocodilia (crocodiles and alligators)
• Squamata (lizards and snakes)
• Testudines (turtles and tortoises)
• Each order contains groups called families, which break down into even smaller groups called genera, and finally into individual species.
• For example, within the order Squamata, the family Colubridae holds many common snakes, while the family Iguanidae holds iguanas.

A Simple Way to See How Many Animals Exist

One simple way to grasp how varied animals are involves looking at a list of animals, like one sorted in alphabetical order from Aardvark to Zorse. This large list includes species like:

• The Eagle
• The Eastern Gray Squirrel
• The Echidna
• The Egyptian Cobra
• The Grizzly Bear
• The Guinea Pig

This list shows the huge variety of animals found across the world, which live in different places and fill different roles in nature.

Why Does How We Sort Animals Change?

The classification system receives constant updates as genetic study improves. This genetic work helps to make clear the family relationships that people knew only from looking at body parts before. Trustworthy databases, such as the Catalogue of Life, keep complete and current information on how to sort animal species all over the world. To sum up, the simple "List of Animals" represents more than just names. It shows the organized biological classification that puts the animal kingdom into a clear structure. This structure helps science study and efforts to save animals. This sorting goes from wide phyla down to single species, showing how complex and rich animal life on Earth is.

FAQ

Why do scientists bother sorting animals?

Scientists sort animals to better know how they relate to one another, their traits, in addition to their history of change over time. It makes study and conservation work simpler.

What is the difference between a phylum and a species?

A phylum is a very large group that holds animals with a basic, shared body plan (like Chordata). A species is the most specific group, representing a single type of animal that breeds together (like the Eastern Gray Squirrel).

Do genetic tests change how we sort animals?

Yes, genetic tests give scientists better information about how animals relate. This often leads to scientists moving animals into different groups to better reflect their true family history.
