Echinodermata

Echinodermata is a phylum of marine animals known for their unique features, including a spiny skin and a water vascular system, which helps with movement and feeding. Common examples include starfish, sea urchins, and sea cucumbers. Echinoderms typically have radial symmetry, meaning their bodies are organized around a central point. They play important roles in marine ecosystems as predators, prey, and scavengers. These animals can regenerate lost body parts and have a fascinating ability to adapt to various ocean environments. Overall, echinoderms are essential components of ocean biodiversity.
