Kingdom Animalia: Characteristics, Classifications, Images & Examples (FULL)
Kingdom Animalia or commonly called animal eukaryotic organisms (organisms with complex cells) are multicellular. Unlike plants, animals do not have chlorophyll so they cannot carry out photosynthesis to make their own food. Therefore, animals must find their own food to get energy then the food is digested in the body. This process requires oxygen and emits carbon dioxide as a waste.
Definition of Kingdom Animalia
Kingdom animalia is one of the kingdoms that has the most numerous and varied members. Broadly speaking, kingdom animalia can be grouped into two groups, namely the vertebrate group (vertebrate animals) and the invertebrate group (invertebrate animals. animals ie animal cells do not have cell walls, animals contain many muscle cells for movement and nerve cells that function to respond to each excitatory.
Kingdom Animalia
Characteristics of Kingdom Animalia
Multicellular Living Things (have many cells)
Heterotroph (can not make their own food)
Requires oxygen
Having muscle cells for locomotion and nerve cells for stimulation
Generally sexual reproduction, but some phyla also use asexual reproduction
The form of the Adult is always diploid (2n)
Kingdom Animalia Classification
Kingdom Animalia consists of
Invertebrate group is a group of animals that do not have a backbone.
vertebrate group that has a backbone.
1. Invertebrates
Invertebrate group is divided into several phyla namely Porifera, Coelenterata, Plathyhelminthes, Nemathelminthes, Annelida, Mollusca, Arthropoda and Echinoderms.
1. Phylum Porifera (porous animal / sponge)
Porifera
Multicellular animals with porous bodies, unformed tissue, have skeletons and waterways.
It is heterotrophic by obtaining food in water that enters the body through pores.
Living in the sea, attached to rocks or other objects.
Asexual reproduction by formation of shoots, gemmules (internal shoots) and regeneration. Sexual reproduction by the formation of gametes.
Porifera are classified into three classes based on the framework, namely Hexactinellida, Demospongiae and Calcaera.
Porifera's role as a bath sponge or scrubber, and potentially as a cancer drug.
2. Phylum Coelenterata (Hollow Animal)
Diploblastic multicellular animals whose bodies have formed tissue, in the form of polyps or medusae with stinging tentacles, have a digestive cavity, a simple nervous system and do not have a system of excretion.
Heterotrophic and uses tentacles to catch prey.
Habitat is in the sea
Asexual reproduction by budding formation by polyps and sexual reproduction by gamete formation by medusae or polyps.
Based on the dominant form in the life cycle can be divided into three classes, namely Hydrozoa, Scyphozoa and Anthozoa.

3. Phylum Platyhelminthes (flatworms)
Aselomata triploblastik animals with bilateral symmetry bodies are flat, have a nervous system, a digestive system with one hole, do not have a circulatory system, respiration and excretion.
Live freely in the sea, fresh water, moist or parasitic places in animals and humans.
Hemaphroditic, sexual reproduction by themselves or cross, asexual reproduction with fragmentation followed by regeneration.
The classification is divided into three classes, namely Turbellaria, Trematoda and Cestoda.
4. Phylum Nemathelminthes (Thread Worms)
Pseudoselomata triploblastik animals, bilateral symmetry body elliptical coated cuticle with a complete digestive system, circulatory system by pseudoselomal fluid, do not have a system of respiration and excretion.
Live free or parasitic
Living in wet soils, at the bottom of freshwater or open sea, is parasitic in humans, animals and plants.
Sexual reproduction
Examples of parasitic Nemathelminthes are roundworms, hookworms, pinworms, filarial worms and Trichinella worms.

5. Annelids (roundworms)
Triploblastik selomata animals, bilateral symmetry body segmented, has muscles, a complete digestive system, circulation system, nervous system ladder cord which is a nervous system consisting of the brain ganglia in front of the body close to the pharynx and nerve cords that penetrate segments of the body and have an excretory system. Does not have a respiratory system, is hemaphroditic or gonokoris (male and female genitals separate in different individuals).
Live freely on the seabed, fresh water, soil and moist or parasitic places on vertebrates.
Sexual or asexual reproduction.
Differentiated into 3 classes namely, Polychaeta, Oligochaeta and Hirudinea.

6. Mollusca (Soft Animal)
Selomata triploblastik animals with bilateral symmetry, soft bodied, free living in the sea, fresh water and land.
The body consists of legs, visceral mass and mantle. Shells, a complete digestive system, open and closed circulation systems. The nervous system consists of ganglions and nerve fibers. Respiration with gill or coat cavity. Excretion with nephridia, reproduces sexually internally or externally and is diocese (male and female genitals are in different individuals) or monoseus (male and female genitalia in one individual).
It is divided into 3 classes namely, Gastropoda, Pelecypoda and Cephalopoda.

7. Arthropods (animal limbs)
Trichlastic selomata animals with bilateral symmetry, have broad legs and body, live in a variety of habitats freely, parasitic, commensal or symbiotic.
The body consists of a head (head), thorax (chest) and abdomen (stomach). Exoskeleton (outer frame), diverse number of limbs, well-developed sensory system, cord ladder nervous system (a nervous system consisting of brain ganglia in front of the body close to the pharynx, and nerve cords that penetrate segments of the body), complete digestive system, excretion through tubule malphigi (a channel as a system of excretion in arthropods) or assisted with certain excretion glands.
Respiration uses gills, tracheal or pulmonary beatings. Open circulation system. Diosseous (male and female genitals exist in different individuals) and internal sexual reproduction and ecdysis (the event of cuticle removal) partially metamorphosed.
It is divided into 4 classes based on body and leg structure, namely Arachnoidea, Myriapoda, Crustacea and Insecta.
