June 1, 2008 With the omission of both prokaryotes and protists, Kingdom Animalia generally contains all sorts of animal species. It is estimated that anywhere from nine to ten million exist on Earth – the exact number is not precisely known. Kingdom Animalia includes the following species: mammals, insects, birds, echinoderms, and etcetera. This paper examines the following in particular: elephants, armadillos, termites, butterflies, penguins, hummingbirds, starfishes, and sand dollars. These species not only divide upon the two the same equivalence in characteristics, setting them apart from other species, but includes the fact that all are generally eukaryotic, multicellular, heterotrophic, lack cell walls, are motile, and usually pass through a blastula stage as animals. Elephants and armadillos are just two species out of the vast majority of existing mammals. These two share the same characteristics: warm-blooded; their young are born alive; and have lungs to breathe air. On the other hand, the two have apparent differences. The body characteristics are the most evident. An elephant’s physical characteristics consist of its enormous size, have tusks, and even a trunk. An armadillo, however, is of moderate size, has hard armor-like skin, short legs, and have claws. Also, an elephant’s diet is usually plant flood, considering that it is an herbivore, while an armadillo uses its sharp claws to dig for grubs or insects. The elephant belongs to the Proboscidea, which only contains one family of living animals, the elephants – includes three species: African Bush Elephant, African Forest Elephant, and Asian Elephant. The Proboscidea order classifies animals that feed by its trunk. The armadillo is only family in the order Cingulata, as well as a superorder Xenartha, which also includes anteaters and sloths. The
