Echinodermata is a large and diverse group of marine invertebrates that includes starfish, sea urchins, sea cucumbers, and sand dollars. These animals are found in all oceans and are an important part of the marine ecosystem. Echinoderms have a unique body plan that includes a hard, spiny skin and a five-part radial symmetry. This means that their bodies are divided into five sections that are arranged around a central point. This body plan allows them to move in any direction and to quickly escape predators. Echinoderms have a variety of feeding habits. Some species are scavengers, while others are filter feeders. Some species are predators, while others are herbivores and can also feed on plankton, algae, and small animals. Echinoderms have an interesting reproductive system. In some species, the sexes are separate, while in others, the sexes are combined into one individual. The eggs are fertilized externally, while in others, the eggs are fertilized internally. Echinoderms are an important part of the marine ecosystem. They provide food for other animals, help to keep the ocean floor clean, and provide habitats for other species. They also help to maintain the balance of the ocean's food web.
