Echinoderms are considered the most advanced invertebrates due to their unique characteristics, such as a water vascular system that helps in movement and feeding, as well as tube feet for locomotion and attachment. They also possess a sophisticated nerve net and radial symmetry, which allows for efficient sensory perception and coordination of movements. Additionally, echinoderms exhibit a high degree of internal complexity, including a well-developed coelom and a unique endoskeleton made of ossicles, setting them apart from other invertebrate phyla.
Echinoderms are a group of marine animals that include sea stars, sea urchins, and sand dollars. They have spiny skin and a unique water vascular system that helps them move, feed, and respire. Echinoderms are known for their radial symmetry and can be found in oceans around the world.

The name echinoderm means "spiny skin." Echinoderms have spines of various lengths that cover the outside of their bodies. Most echinoderms are supported and protected by an internal skeleton made up of bonelike plates. Echinoderms have a simple nervous system but don't have heads or brains.
Hydrogen is the element with unique properties that doesn't fit in any group.
Animals with irregular shapes are commonly referred to as "asymmetrical" or "irregular" animals. This term is often used in biology to describe organisms that do not have a symmetrical body structure, such as certain types of sponges, some echinoderms like sea cucumbers, and various invertebrates. Their unique shapes can result from adaptations to their environments or specific ecological roles.
