have resulted in different phyla, ranging from basic structures, like sponges to advance systems, like that of an octopus. Porifera is the most simplistic phylum under the kingdom Animalia. The sponges have no tissue layers, but instead an interior and exterior layer with a gelatinous middle layer that separates the two. They are the only phylum with asymmetrical symmetry. Throughout the advancing phyla it will be shown this trait is lost. Porifera lacks a proper digestive system, but a canal system
food and waste. These facts and information will show proof of the many characteristics and bodily functions that these three animals display. I found it interesting that the most recognized organisms in the Porifera Phylum are called sponges. In fact, Porifera is the oldest phylum in the kingdom of Animalia, and have been around for the last six hundred
Annelids: I learned that the phylum Annelids can consist of many creatures such as earthworms, leeches, and scale worms can adapt to a variety of environments. Annelids’ bodies are divided into segments which are seen as rings by the naked eye. They have muscles which help them move by contracting their longitudinal and circular muscles. When Annelids take in food, the food particles travel through one end of the body and are excreted out the other side. The video enhanced my understanding about
Introduction Fossil records indicate life has existed on this planet for at least 3.8 billion years. Most species that have ever existed are now extinct, yet the diversity of life on Earth is still so tremendous and complex scientists estimate there are 10-100 million species yet to be documented. Those that have been documented, have been categorized it into three domains, six kingdoms, twenty-nine phyla, and countless more subdivisions. Seemingly in spite of this diversity, a common ancestry unites
Phylum chordates are a taxonomic rank below kingdom that includes organisms such as mammals, fish, birds, reptiles, amphibians, all vertebrates, tunicates, and cephalochordates. To be in the phylum of chordates you must at some point in your development of life have a dorsal nerve, or hollow nerve cord which is in the central nervous system that acts as a support to the locomotion system. I will discuss the different kind of organisms along with some characteristics of the organisms found in the
Jellyfish, of the Phylum Cnidaria, are an interesting and well developed species. Although they are invertebrates, they are similar to human beings in that they contain an intricate central nervous system that enables them a common perception of their environment. It is understood that several species of jellyfish utilize their nerve net in order to respond to common features of their aquatic habitat, such as: depth of water, light, sound and temperature. They use utilize information from these environmental
Echinoderm (meaning Spiny skinned) is a diverse group of invertebrates belonging to the phylum Echinodermata. Phylum Echinodermata consists of five main classes that are divided into 7,500 extant species and approximately 13,000 known extinct species, including several classes that were discovered through fossils. The five main classes are proposed to have evolved from a common metazoan ancestor approximately 500 million years ago during the early Palaeozoic period (Britannica, 2014). Echinoderms
INTRODUCTION: The Animal Kingdom is generally believed to have originated in Archeozoic oceans long before the first fossil record. Every major phylum of animals has at least some marine representatives; some groups, such as cnidarians and echinoderms, are largely or entirely marine lives. From the ancestral marine environment, different groups of animals have invaded fresh water; some have moved onto land. There are over a million described species of animals. About 5% of this number are consists

Respiration is crucial in the survival of all animals, relating the Phylum Chordata, Class Mammalia to the Phylum Mollusca, on a parallel level. Although each animal in these taxonomic groups have varied ways of obtaining the oxygen they use to make energy to get food, both result in the same end product, which provides the animal with life
fall into the plant, animal, or fungi kingdom. Kingdoms are then divided into phylum. This division is based body type and skeletal organization. Phylum are then divided into subphylum. Subphylum are divided into classes, orders, genus, and then species. This system of classification is still used by scientists today[1]. In this assignment, seven organisms are presented which are to be classified into phylum or class based on a dichotomous key. The first organism presented in this assignment
of the dusky gopher frog is as follows: Kingdom: Animalia, Phylum: Chordata, Class: Amphibia, Order: Anura, Family: Ranidae, Genus: Lithobates, Species: L. sevosus. A few of the dusky gopher frogs relatives include the rio chipillico frog which can be found in Ecuador and Peru. This frogs natural habitats are being threatened by agricultural expansion. The classification of the rio chipillico frog is as follows: Kingdom: Animalia, Phylum: Chordata, Class: Amphibia, Order: Anura, Family: Ranidae,

The Swell Shark’s taxonomy is as follows: it is a member of the domain Eukarya, the kingdom Animalia, the phylum Chordata, the class Chondrichthyes, the order Carcharhiniformes, the family Scylorhinidae, and the genus Cephaloscyllium (IUCN Redlist.org).
Cnidaria is a large phylum composed of some of the most beautiful of all the salt and freshwater organisms: the true jellyfish, box jellyfish, coral and sea anemones, and hydra. Although Cnidaria is an incredibly diverse group of animals, there are several traits that link them together. Most cnidarians are dipoblastic, which means that they are composed of only two layers of cells. The outer layer is known as the ectoderm or epidermis, and the inner layer is known as the endoderm or gastrodermis
and its wild, feral, and overall unvarying establishment. This is shown in all forms of living matter, from even the most basic amoeba to as large a creature as a blue whale. One overlooked group in the animal kingdom is the phylum, arthropoda despite being the largest phylum, encompassing about 84 percent of all known species of animals. These are certainly not the first thought when one is asked what an animal is; a person usually thinks of an animal such as the lion or a dog. However,

(Glaessner 67)The nature of these soft-bodied fossils justifies the characterization of the Precambrian as the "age of the jellyfish," however the term jellyfish only refers to a number of diverse forms, which belong to the Phylum Cnideria.

The Great Barrier Reef What is the Great Barrier Reef? The Great Barrier Reef is a huge, colourful and bright coral reef, situated off the coast of Queensland in the Coral Sea. It is so big that it is the only living thing that can be seen from Space! It consists of over 2,900 individual reefs and 900 islands that stretch over 348,700 km². It is in a wet, tropical climate with reasonably warm Winters and a high humidity in the Summer. Water temperatures span from 14 degrees Celsius in the Winter
Evolution has become a controversial topic over the years and with dominant evidence, we know that it takes place even today. Evolution is a slow and time consuming process which is why we do not observe it instantaneously. To observe evolutionary patterns, you must take it in large amounts of time. Charles Darwin is known as the “Father of Evolution” and discovered much of the evolutionary concepts that we have an understanding. Evolution has branches that include change with humans, animals, sex
Flatworms belong to the phylum Platyhelminthes. They have the simplest body plan of all bilaterally symmetrical animals. They are called flatworms because their bodies are compressed. The mouth is the only opening into the digestive cavity the flatworms have. Food is taken in through this hole and wastes are discharged also through this hole. Flatworms have a well-defined nervous, muscular, excretory, and reproductive system. The flatworm distributes the food it digests through a digestive tube that
The aetobatus narinari, or more commonly known as the spotted eagle ray, is a member of the chordata phylum. (2) Being a part of the chordata phylum means they have unique characteristics such as: their notochord, a dorsal hollow nerve chord, pharyngeal slits, and a post anal tail. There are many reasons this animal is so intriguing, including its diversity and health, physiology, behaviour, and ecological challenges it faces. Spotted eagle rays are found throughout tropical warm waters in: the
types of crustaceans, let's take a moment to go over the characteristics and anatomy they share. Crustaceans belong to the Arthropoda Phylum, which includes critters like ants, spiders, and centipedes. I know! Crazy to think that a delicious crab is in the same group as a spider! But they share similar characteristics. For starters, members of the Arthropoda Phylum do not have a backbone like you and me, so they are called __invertebrates__. And, as mentioned earlier, their skeleton is external
