Free Example of Kingdom Plantae and Animalia Essay.
ON THE CLASSIFICATION OF THE ANIMAL KINGDOM.1 BY PROFESSOR T. H. HUXLEY.. The present essay is ail attempt to classify the known facts of animal structure, including the development of that structure, without reference to phylogeny, anld, therefore, to form a classifi- catiou of the animal kingdom which will hold good, however much phylogenic speculations m,,ay vary. Animals are primarily.
Turbellaria is a class of free-living flatworms (often called planarians). The other two groups are parasitic: Trematoda (flukes) and Cestoda (tapeworms). These parasitic kinds constitute the majority of species of flatworms (figure 23.14). We may consider this form of nutrition rather unusual, but of all the kinds of animals in the world, more are parasites than not.
Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Europe, Middle East, Asia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
This is an example of filamentous growth. This kind of growth can be difficult to describe using all of the bacterial colony morphology characteristics.
Animal - Animal - Animal diversity: The diverse appearance of animals is mostly superficial; the bewildering variety of known forms, some truly bizarre, can be assorted among a mere half-dozen basic body plans. These plans are established during the embryonic stages of development and limit the size and complexity of the animals. Symmetry, number and relative development of tissue layers.
Starfish are found in all the oceans of the world, which shouldn’t really come as a surprise considering that there are more than 1,500 recognized species on the planet. Besides the Pacific Ocean, the Indian Ocean, and the Atlantic Ocean, starfish are also found in the Arctic Ocean as well as the region where the Southern Ocean and the Antarctic Ocean merge. If they are only found in oceans.
Animal Diversity Part I Introduction One of the primary goals of the second half of Biol 106 is to understand evolutionary relationships among animals and to gain an appreciation for the diversity of animal form and function. The huge diversity of animals requires us to divide our survey of different animals into a number of labs. Because of time limitations, we will consider only the major.
