Most animal phyla originated in a relatively brief span of geological time‚ however the diversity among them is extraordinary. Every organism is very unique a detailed in certain ways‚ comparisons of certain types of organisms can be very difficult. The class in which will be compared is that of the invertebrates. The main difference between coelomate and acoelomate body plans are that coelomates have a true coelom‚ which is a fluid-filled body cavity completely lined by tissue which is derived

Pill bugs are knows as woodlice‚sowbugs‚ and roly-polies.Despite the name Pill bugs aren’t actually “bugs” they are classified as terrestrial isopods and fall under the class Crustacea.This class also falls under an even larger group called Arthropoda. Arthropoda consists of many Arthropods that have bilateral symmetry‚segmented bodies‚exoskeletons‚jointed appendages‚and numerous pairs of limbs.Pill bugs also have a flattened or round-backed profile‚seven pairs of legs‚ and sharply-angled antennae

body plan and segmentation. The other hypothesis is that arthropods evolved more recently from a nematode ancestor than an annelid like ancestor because of their shared ecdysis trait. Hypothesis 1 Nematoda Annalida Arthropoda Hypothesis 2 Annalida Nematoda Arthropoda Reasoning: The morphological data that supports hypothesis one is that annelids and arthropods both have segmented bodies‚ dorsal circulatory systems‚ ventral nervous systems‚ and appendages. The morphological data that

CHAPTER 4 ANIMAL KINGDOM 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 now. The classification helps to assign a systematic position to newly described

Taxonomy Scientists use taxonomy to classify organisms and assign each organism a universally accepted name. They do this by using a Dichotomous Key to classify organisms‚ the binary nomenclature‚ DNA‚ and RNA. In the taxonomic nomenclature naming system‚ there are different levels called a taxon (taxa plural) or taxonomic category. The different levels to the taxonomic nomenclature naming system are called: Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ and Species

length of one-half inches and a wing span of 0.0079 inches. As all insects‚ the wasp has bilateral symmetry‚ an exoskeleton‚ two eyes‚ six legs‚ and three body parts. It has two antenna and 2 wings. The wasp is part of the Animalia Kingdom‚ Arthropoda Phylum & Insecta Class. The life cycle of a wasp begins with an egg and ends sometime between 12 days and 12 months later as an adult wasp. The queen wasp lays eggs into the cell of the nest. Each egg will hatch in its own cell becoming larva
