AFritzke14. These include chemoreceptors, tactile organs, terminal tentacles, etc. Echinoderms move by alternately contracting muscles that force water into the tube feet, causing them to extend and push against the ground, then relaxing to allow the feet to retract. However, both molluscs and echinoderms are triploblastic, and they possess a complete digestive system.

The mouth frame is well developed and adambulacral type. They have poorly developed sense organs. 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 intertidal starfish or sea urchin.

Identification of the major issues surrounding the organization or individuals involved with the organization. Some, like the sunflower sea star, are voracious predators that are quick and nimble when in pursuit of prey. Ambulacral grooves usually not for food gathering. This phylum includes animals like Jellyfish, Hydra, Corals, etc. Radial symmetry appears to be an advantage to the mostly bottom-dwelling echinoderms, who can thus feed in every direction.
