Animal Kingdom is characterized by multicellular, eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic), hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till

Oct 31, 2023 · Even though members of the animal kingdom are incredibly diverse, most animals share certain features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have a complex tissue structure with differentiated and specialized tissues.
A Brief Classification of the Animal Kingdom KINGDOM ANIMALIA Multicellular eukaryotic organisms, usually motile, lacking chloroplasts and developing from a hollow ball of cells (blastula). Phylum PORIFERA. Sponges. Animals possessing specialized cells but no organized tissues. Phylum MESOZOA. A small group of species, containing organisms with only a few
A major characteristic unique to the animal kingdom is the presence of differentiated tissues, such as nerve, muscle, and connective tissues, which are specialized to perform specific functions. Most animals undergo sexual reproduction, leading to a series of developmental embryonic stages that are relatively similar across the animal kingdom.
