What are five features that characterize echinoderms?
Although all living echinoderms have a pentamerous (five-part) radial symmetry, an internal skeleton, and a water-vascular system derived from the coelom (central cavity), their general appearance ranges from that of the stemmed, flowerlike sea lilies, to the wormlike, burrowing sea cucumbers, to the heavily armoured ...
What are the classes of Echinodermata?

Is a larval forms of phylum echinodermata?
Class Holothuroidea demonstrate two larval stages, namely, auricularia and doliolaria larvae. ➢ Auricularia larva has striking resemblance with bipinnaria of Asteroidea as it also possesses 4 or 5 pairs of ciliated arms for swimming and has a well- developed mouth, gut and anus.
What do all 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.
