The 7 Main Types of Animals And Their Characteristics
There are many different types of animals in the world, but some of the largest include:
🐆
Mammals
Mammals are a group of vertebrate animals constituting the class Mammalia. Animals that are considered mammals include warm-blooded vertebrates with fur or fur and whose offspring drink milk. Unlike other animals such as birds and insects, their young drink milk from their mothers' bodies. This is one of the important ways to tell if an animal is a mammal.

Reptiles
Reptiles, as most commonly defined, are the animals in the class Reptilia (a paraplegic grouping comprising all sauropsid amniotic except Ave). Living reptiles comprise turtles, crocodiles, soulmates and rhynchocephalians. This is a diverse group with more than 11,000 different species and a huge representation in the fossil record. Once the dominant land vertebrates on the planet, reptiles still occupy just about every single ecosystem outside the extreme north and south.
🐠
Fish
Fish are aquatic, cranial, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish, as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleports.
🦜
Birds
Birds, members of the class Aves, include more than 10,400 living species. Their feathers distinguish them from all other classes of animal; no other animals on earth have them. If you see an animal with feathers, it’s undoubtedly a bird. Like mammals, birds are warm-blooded vertebrates with four-chambered hearts. However, they are more closely related to reptiles and are believed to have evolved from dinosaurs.
🐸
Amphibians
The official class of amphibians is Amphibia. To have the classification of an amphibian, an animal must be a vertebrate, require water to survive, be cold-blooded, and spend time both on land and in water. Though other animals only live on land or in the water, amphibians have the unique ability to thrive equally in both. Amphibians cover over 6,000 different species across the globe, but about 90% are frogs.
🐙
Invertebrates
The definition of an invertebrate is any animal that does not have a backbone or vertebral column. The most prolific and easily recognizable members of the invertebrate family are insects. It’s estimated that upwards of 30 million individual species of invertebrates may exist accounting for between 90-95 percent of all organisms on the planet.
🦋
Insects
All insects are part of the taxonomical phylum Arthropoda, and they are collectively referred to as arthropods. It is common to see this name misspelled as “anthropod,” but this is not the correct term. They can be found in nearly every environment on the planet, and they currently account for over half of all known living organisms in the world. They have undergone many cycles of evolution depending on the resources available to them.
