Also asked, what do echinoderms have in common?
All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions.
Furthermore, why are echinoderms considered closer to chordates than any other phylum? Echinoderms are considered closer to chordates than to any other phylum because the coelom of the animals in this phylum is made from the digestive tube and the endoskeleton is made of 95% of calcium carbonate just like in chordates.
Considering this, why are starfish and chordates closely related?
Chordates are eucoelomate deuterostomes, and probably share a common ancestor with echinoderms. Three important characteristics unite the Phylum Chordata. At some point in their life cycle, all chordates have a notochord, a dorsal hollow nerve cord, and pharyngeal gill slits.
What are chordates most closely related to?
Echinoderms represent the phylum most closely related to chordates They are. You can ask !
