Classification of Marine Organisms

Classification is a way of categorizing organisms that enables an easy process of identification of such organisms. All living things are classified by grouping them under specific categories. The grouping is done based on the close relativeness of the organisms. The classification tool requires knowledge of characteristics, differences, and similarities between different organisms.
