Kingdom Animalia is a vast and varied kingdom, containing millions of species of animals. In this article, we will explore the classification of kingdom animalia, the characteristics of kingdom animalia, and examples of kingdom animalia.
Kingdom Animalia is classified into several different phyla, each with its own unique characteristics. Some common phyla of Kingdom Animalia include Arthropoda (insects), vertebrates (mammals, reptiles, fish), and Mollusca (snails, squid, octopuses).
The characteristics of Kingdom Animalia vary depending on the phylum, but some common features include the presence of locomotion (movement), the ability to sense the environment, and the ability to feed and digest food. Some common examples of Kingdom Animalia include dogs, cats, mice, birds, snakes, and turtles.
Classification
- The most common phyla are vertebrates, Arthropods, Molluscs, and Annelids. Each one of them has different abilities that make them unique.
- Animals with backbone are called Vertebrates. Like fish, amphibians, reptiles, birds, and mammals are their examples. Vertebrates are distinguished from other animals by their skeletal system and their nervous system.
- Arthropods are animals that have an exoskeleton and jointed appendages. This includes animals such as insects, crustaceans, spiders, and centipedes. Arthropods are distinguished from other animals by their segmented body and their jointed limbs.
- Molluscs are animals that have a soft body with a hard shell. This includes animals such as snails, slugs, octopuses, and squids. Molluscs are distinguished from other animals by their mantle and their muscular foot.
- Annelids are animals that have a segmented body with setae (bristles). This includes earthworms and leeches. Annelids are distinguished from other animals by their coelom (body cavity) and their metameres (segments).
Characteristics
- The Kingdom Animalia is the largest and most diverse kingdom of all living organisms on Earth.
- There are over 1.3 million species of animals, making it the most populous kingdom.
- Animals can be found in every environment on the planet, from the coldest polar regions to the hottest deserts.
- Animals are distinguished from other living things by their ability to move voluntarily. This means that they can control their own movement in response to their environment. All animals are heterotrophic, meaning that they cannot produce their own food and must rely on other organisms for nourishment.
- Animals can be divided into two main groups: vertebrates and invertebrates. Vertebrates are animals with a backbone, while invertebrates are animals without a backbone.
- The vast majority of animals (over 95%) are invertebrates.
- The four main characteristics of Kingdom Animalia are: cell type, mode of nutrition, body symmetry, and presence or absence of segmentation.
Examples
There are many different types of animals in the world, but they can all be classified into the Kingdom Animalia. This kingdom is characterized by multicellular, eukaryotic cells, and a lack of cell walls.
Animals are heterotrophic, meaning they rely on other organisms for food. They are also distinguished from other eukaryotes by their ability to move independently.
Some examples of animals in the Kingdom Animalia include
mammals, reptiles, amphibians, fish, birds, and insects. These animals all have
different characteristics that make them unique, but they all fit into the Kingdom Animalia.
