Echinoderms are protected by their spiny skins, but are still preyed upon by some types of shells, fish, crabs, shrimps, among many other.

they live in the water so they have a clear coat

Echinoderms, such as sea stars and sea urchins, have an endoskeleton made of hard plates called ossicles that lie inside their bodies. Although this endoskeleton is internal, it functions similarly to an exoskeleton by providing support and protection. It allows echinoderms to control their body shape and movement, just like an exoskeleton does for other invertebrates.
starfish,brittlestar,or a sea urchin(Echinoderms).
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
Respiratory tree is present in echinoderms eg. sea urchin it helps in respiration and protection from predators by evisceration .
Echinoderms, such as seastars and sea urchins, use their tube feet to move. Tube feet have suction discs which allows the echinoderm to crawl or stick to various surfaces.
Echinoderms are in the Animalia kingdom.
echinoderms
In echinoderms, such as starfish, an ossicle is a bony plate providing structure and protection. It is covered by an epidermis and considered part of the hard endoskeleton where the bony (calcite) plates (ossicles) are connected by collagen fibers.
they use sucker like part to catch prey
As of yet, there is no known species of parasitic echinoderms.
The scientific name for Echinoderms is Echinodermata.
Yes Eventually echinoderms do live in water.
