The phylum that includes starfish (sea stars), sea cucumbers, and sea urchins is Echinodermata. This group is characterized by its radial symmetry, a water vascular system, and a calcareous endoskeleton. Echinoderms are primarily marine animals and play important roles in their ecosystems as predators, scavengers, and prey. They also exhibit unique regenerative abilities, allowing them to regrow lost body parts.
