Scientific Taxonomy and Earth's BiodiversityJessica MacRobertsAxia College of University of PhoenixSCI 230IntroductionKingdom Animalia contains all animal species .This paper describes the biodiversity of mammals, insects, birds, and echinoderms. This includes the description of the following species in particular: elephants, armadillos, termites, butterflies, penguins, hummingbirds, starfishes, and sand dollars. While these species have different characteristics, the fact is that all of them are generally eukaryotic, multi-cellular, heterotrophic, lack cell walls, are motile, and usually pass through a blastula stage as animals.MammalsElephants 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 breathing organ. Despite their similarities, 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 (Myers, 2008). An armadillo however, is of moderate size, has hard armor-like skin, short legs, and have claws (Myers, 2008). In addition, 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 (National Geographic Society, 2008).The elephant belongs to the Proboscidea, which only contains one family of living animals, the elephants - includes three species such as African Bush Elephant, Asian Elephant, and African Forest Elephant (McKenzie, P. (2001). The Proboscidea order classifies animals that feed by their trunks. The armadillo is the only family in the order Cingulata and in a super order Xenartha. Xenartha, also includes animals such as anteaters and sloths. The Cingulata order classifies animals with girdle like shells.InsectsInsects include many species, in particular, the termite and butterfly. These two insects generally share these characteristics: an exoskeleton, three major body parts (head, thorax, and abdomen), and antennas (Reach Out, 2004). However, they differ as well. A termite's diet usually feeds upon dead plant material (wood, leaf litter, soil, animal dung, and crops), while a butterfly usually sips liquid food through a tube-like proboscis, such as from rotting fruits or some even prefer animal flesh or fluids (Col, 2008). Another major difference exists within the fact that termites are typically seen as pests to humans, for they cause much damage to buildings, crops, and plantation forests, while butterflies are viewed as being pleasant and attractive to the eye. A termite is classified under the order Isoptera, which includes only termites; however they are related to cockroaches and mantids in the super order Dictyoptera (Myers, 2008). The order Isoptera simply means "termites". Butterflies are under the order Lepidoptera, which includes eriocraniid...
