Certainly no creature in the sea is odder than the common sea cucumber.
All living creature, especially human beings, have their【C1】________ , but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other【C2】________ , eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered【C3】________ edible by gourmets? For some fifty million years, despite all its eccentricities, the sea cucumber has【C4】________ on its diet of mud. It is【C5】________ 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 suck up mud or sand and digest whatever【C6】________ are present. Sea cucumbers come in a variety of colors, ranging from black to reddish brown to sand color and nearly white. One form even has vivid purple tentacles. Usually the creatures are cucumber shaped—hence their name—and because they are typically rock inhabitants, this shape,【C7】________ with flexibility, enables them to squeeze into crevices where they are safe from【C8】________ and ocean currents. The most【C9】________ thing about the sea cucumber is the way it【C10】________ itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into water. It also casts off attached structures such as tentacles. The sea cucumber will remove its organs and regenerate itself if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.
A. nutrients B. spectacular C. peculiarities D. adoptable
E. defends F. eccentricities G. exactly H. predators
