This is not designed to be some kind of long-winded encyclopedia. Yes, one of the goals is to be more knowledgeable about animals, but also, we give practical information and useful tips on how to spot and observe these wonderful creatures.

Exploring Wildlife

If like me you’re a nature lover, you know how thrilling it feels to encounter the majestic, awe-inspiring, sometimes strange species that call Earth home. Our goal with this new section is to spark your curiosity and, who knows, ignite your passion for the animal kingdom and encourage you to get out there, and include wildlife watching in your trips. Promoting responsible and sustainable wildlife tourism is one of our core values.

Here, we are all about exploring the incredible diversity of the Animal Kingdom. Because, let’s face it, we are all able to give a sizeable list of animals that we know, but there are so many creatures out there that most of use have never heard of!

So let’s jump in and learn more about them!

Classification of Animals

Our planet hosts a breathtaking array of animal species, believed to number in the millions.

In order to facilitate research and understand the connections among them, scientists have arranged these species into various classifications.


Taxonomy, the scientific method of grouping living organisms based on their shared traits into categories known as ‘taxa’ (the plural of ‘taxon’), plays a crucial role in this process.

The hierarchy of classification comprises eight main levels:

  1. Domain
  2. Kingdom
  3. Phylum
  4. Class
  5. Order
  6. Family
  7. Genus
  8. Species

Given the intricacies of life on Earth, additional levels such as superclasses, suborders, or subspecies are sometimes needed and incorporated.

Carl Linnaeus, an 18th-century Swedish botanist, is credited with the development of this system, hence it’s referred to as Linnean Taxonomy.

Take, for instance, the full taxonomic classification for a lion:

  • Domain: Eukaryota
  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Mammalia
  • Order: Carnivora
  • Suborder: Feliformia
  • Family: Felidae
  • Subfamily: Pantherinae
  • Genus: Panthera
  • Species: leo

Linnaeus also introduced the binomial nomenclature, a method of naming organisms using their Genus and species names. So, a lion is scientifically known as Panthera leo. As a standard practice, these Latin names are italicized.

The use of Latin, an extinct language, ensures that scientific names of species will remain consistent as the language won’t evolve further.

Vertebrates & Invertebrates

Animals are primarily divided into two broad categories. Vertebrates have a spine or backbone, while invertebrates lack one.

Classification of Animals EJ

Vertebrates belong to the phylum Chordata and are further subdivided into seven classes, accommodating both warm and cold-blooded species:

  • class Mammalia – Mammals
  • class Aves – Birds
  • class Agnatha – Jawless fish
  • class Chondrichthyes – Cartilaginous fish
  • class Osteichthyes – Bony fish
  • class Reptilia – Reptiles
  • class Amphibia – Amphibians

In contrast, invertebrates are grouped into several phyla, including:

  • phylum Porifera – Poriferans
  • phylum Echinodermata – Echinoderms
  • phylum Cnidaria – Cnidarians
  • phylum Mollusca – Mollusks
  • phylum Annelida – Annelids or segmented worms
  • phylum Platyhelminthes – Flatworms
  • phylum Nematoda – Nematodes or roundworms
  • phylum Arthropoda – Arthropods, which is further divided into subphyla and classes such as Arachnida, Crustacea, Insecta, and Myriapoda.

Frequently Asked Questions About Animals

Among the 8.7 million various species contributing to the biodiversity of our planet, the estimated count of animal species ranges from one to two million.

In a 2009 study, mathematician and animal rights activist Brian Tomasik estimated the total number of individual animals living on Earth. His computations suggested a figure of 20 quintillion, equivalent to 20 billion billion or 20,000,121,091,000,000,000 animals.

Indeed, humans are classified as animals. We belong to the categories of vertebrates, mammals, and primates, sharing these classifications with creatures like chimpanzees and bonobos, our nearest genetic relatives. Our advanced cognitive abilities often make us perceive ourselves as separate. An insightful article discussing this topic can be found on Science Focus.
