Cnidaria exhibit a tissue-level organization, characterized by the presence of specialized cells and tissues but lacking true organs. These organisms, which include jellyfish, corals, and sea anemones, possess two main body forms: polyp and medusa. Their body structure is organized around a central cavity called the gastrovascular cavity, which serves both digestive and circulatory functions. Additionally, cnidarians have a simple nerve net, allowing for basic responses to stimuli.
