Kingdom Animalia
- Kingdom Animalia is also called as Metazoa
- Does not contain the prokaryotes or the protists
- All members of Animalia are multicellular and heterotrophs (rely directly or indirectly on other organisms for their nourishment)
- Most of the K.Animalia ingest and digest food in their internal cavity
- Animal cells lack the rigid cell walls that characterze plant cells
- Bodies of most animals are made up of cells organized into tissues and each tissue is further organized into specialized organs
- Most Animals are capable of complex and relatively rapid movement compared to plants and other organisms
- Most Animals reproduce sexually
- Most Animals are diploid
- Between 3 to 30 million species of animals inhabit in the Earth, only a rough estimate could be made
- Range in size from microscopic animals such as plankton to massive blue whales.
- Largest subgroup of animals is the insects
- Animals are thought to have evolved from flagellate protozoa and the oldest animal fossils date back 600 million years, to the latter part of precambrian.
- Most major groups of animals evolved during the Cambrian period
