问题     Certainly no creature in the sea is【C1】______than the common sea cucumber. All living creatures, especially human beings, have their peculiarities, but【C2】______about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other【C3】______, eats mud, feeds almost【C4】______day and night but can live without eating for long periods, and can be poisonous【C5】______is considered supremely edible by gourmets? For some fifty million years, despite all its eccentricities, the sea cucumber has【C6】______on its diet of mud. It is【C7】______enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats.
    Common in cool water on both Atlantic and Pacific shores, it has the ability to【C8】______upmud or sand and digest whatever【C9】______are present. Sea cucumbers come in a【C10】______of colors,【C11】______from black to reddish brown【C12】______sand color and nearly white. One form even has vivid purple tentacles. Usually the creatures are cucumber shaped—【C13】______their name—and because they are typically rock inhabitants, this【C14】______,【C15】______with flexibility, enables them to squeeze into crevices where they are safe from【C16】______and ocean currents. The most【C17】______thing about the sea cucumber is the way it【C18】______itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into water. It also casts【C19】______attached structures such as tentacles. The sea cucumber will remove its organs and regenerate itself if it is attacked or【C20】______touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted [br] 【C15】
