Echinoderms are a diverse group of marine organisms. The name means "spiny-skin" and is appropriate because the internal skeleton of the animals in this group has spines, called ossicles, that usually protrude through the skin.. Echinoderms have a unique water vascular system that includes a network of tubes that connect many hollow tube feet. Water flow is controlled by muscle contractions and directs the movement and feeding of these animals. 1. Observe the display of specimens at the counter and answer the questions below. a.

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.
