A sea cucumber is a Herbivore.

Echinoderms are a category of sea invertebrates; there are 5 groups of echinoderms, Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea. A sea cucumber is a holothuroidea; their lengthy body surrounded by leathery skin identifies holothuroideas. A sea lily is a crinoidea; crinoidea feed off the seabed with a mouth at the top of their body.

The Sea Cucumber is a soft-bodied invertebrate that is related to the starfish and sea urchins. There are over 1100 species that are found worldwide in intertidal zones as well as deep waters.

Yes; all over its body. But its muscles can also move the spines!

The word "ossicle" means "little bone"

The sea cucumber has calcified structures just under the skin which are called microscopic ossicles or sclerietes. There are many of these ossicles which are remnants of a previous endoskeleton.

Sea Cucumbers have a variety of colors, depending on the species. Most are a light orange, brownish-orange, or a reddish-brown. Also, some species have a projections similar to spikes which are black.

The warty sea cucumber can grow from 9 to eleven inches in length and get 4 to 5 inches tall. Other sea cucumbers (like the California Sea Cucumber) can grow to be about 16 inches. There is no overall average length of all the Sea Cucumbers. Every Species has its own length.

Sea Cucumbers, in fact, do not have feet.

According to the Wikipedia article "Holothuroidea", sea cucumbers can defend themselves two ways: firstly by "expelling their sticky cuvierian tubules" to entangle predators; and by secreting a poisonous soap-like substance called holothurin into the surrounding water. According to the same article, they are also able to squeeze into extremely small spaces. http:/en.wikipedia.org/wiki/Holothuroidea.they can also camoflage.

Although sea cucumbers are one of the safest animals on the reef to touch, the numerous white Cuvierian tubules, which some eject when irritated, contain a toxin which can cause blindness if it comes into contact with the eyes. This toxin may also be present on the skin so you should wash your hands after handling these creatures

of course. They are eaten alive or cooked in several countries.
