Kingdom Animalia: The Classification of Animals

Animals are categorized into different groups. The Kingdom Animalia is the largest group and it includes all of the animals that have backbones. They can be divided into vertebrates and invertebrates. Vertebrates contain all of the animals with a spinal cord in their backbone, including mammals, birds, reptiles, amphibians, and fish. All of these animals are able to move their bodies freely from side to side or up and down in relation to their head. Invertebrates do not have a spinal column nor can they move their body freely relative to their head. This includes small organisms like insects and other arthropods such as crustaceans and spiders as well as mollusks like snails and octopuses. In this blog post, I will be discussing the classification of animals from my perspective as an animal lover!

Vertebrates

Vertebrates are so diverse and include mammals, birds, reptiles, amphibians, and fish. All vertebrates have a backbone. Mammals are warm-blooded animals that nourish their young with milk produced by mammary glands in females. They can be live-bearers or egg-layers or can do both. There are 2 main types of mammals: humans and other primates, and viets such as elephants, lions, rhinoceroses, and bats. Birds are warm-blooded animals that fly using wings instead of arms or legs to get them up into the air. There are many different kinds of birds including those with feathers (examples: peacocks) and those without feathers (examples: penguins). Reptiles live on land as well as in water (examples: turtles) or on hot soil (example: snakes). Reptiles have dry scaly skin that may also be covered in scales or plates which can come in a variety of colors. Amphibians include frogs, salamanders, newts, and toads who live both in water and on land but will change from aquatic life to terrestrial one if necessary for survival. Amphibians breathe through their skin which is often moistened by water. Fish live in water but some can survive on land for periods of time such as salmon who migrate upstream to spawn within freshwater rivers every year after living their entire lives at sea!

Invertebrates

Invertebrates are animals that do not have a spinal column and cannot move their body freely in relation to their head. This includes small organisms like insects and other arthropods such as crustaceans and spiders as well as mollusks like snails and octopuses. Invertebrate animals are also classified as protostomes or deuterostomes, with protostomes being the more primitive group.

There are four different types of invertebrates that I would like to discuss in this blog post: Protozoa, Cnidarians, Echinoderms, and Molluscs.

The first type of invertebrate is called a Protozoa. These critters can be unicellular or multicellular and they typically reproduce asexually by binary fission. There are over 20,000 species of these bugs!

The second type of invertebrate is called a Cnidarian. Cnidarians are animals that produce stinging cells which act like venom in some cases; hence the name “Cnidarians.” These invertebrates also have sensory organs at their base called cnidae which function to stun prey and defend against predators. There are two types of Cnidarians: Jellyfish-type and Anemone-type Cnidarias. The first type has a sac for storing food, tentacles for catching prey, an umbrella-shaped body with a gastrovascular cavity surrounded by

Conclusion

In this post, I will be discussing the classification of animals. I will be discussing what kingdom they are in and what types of animals are in that kingdom.

Kingdom Animalia

The classification of animals is called Kingdom Animalia. There are two main parts to this kingdom. They are the vertebrates and invertebrates. The two types of animals that make up this classification are fish, mammals, birds, amphibians, reptiles, and so on.

Vertebrates

The vertebrates are those animals that have a backbone. They include fish, amphibians, reptiles, mammals, and so on. They all have a backbone and a spinal cord. This means that they have a brain in the head and a spinal cord coming from the brain to the tail. Most vertebrate animals also have a heart with four chambers. These chambers are called the right atrium, left atrium, right ventricle, and left ventricle.

Invertebrates

The invertebrates do not have a backbone. They do not have a spinal cord or brain in the head. They do not have a four-chambered heart like vertebrates. Included in this classification are spiders, crustaceans,
