Let us learn about kingdom animalia
Each animal is the members of the Kingdom Animalia & also called Metazoa. This kingdom animalia does not contain the prokaryotes Kingdom Monera, includes bacteria, blue-green algae or the protists Kingdom Protista, and includes unicellular eukaryotic organisms. All members of the Animalia are multicellular, & all are heterotrophs which are, they rely directly or indirectly on other organisms for their nourishment. Most ingest food & digest it in an internal cavity.
With over 2 million different kinds of animals Kingdom Animalia is the biggest & largest of the kingdoms. But when we think of an "animal", what image comes to our mind? While animals like bears, fish, & birds are the most familiar to us, over half of all the animals on Earth belong to a group of animals known as "arthropods". Arthropods include animals such as centipedes, insects, crabs, & spiders. This means that the preponderance of animals come from a group of critters that give most folks the creeps!
