Popularlyknown as starfish, sea stars are actually echinoderms, closely relatedto sea urchins and sand dollars.───海星实际上是棘皮动物，和海胆和饼海胆是近亲。
These small, spiny echinoderms are found in oceans all over the world.───这些小的，多刺的棘皮动物能够找到在全世界的海洋。
echinoderms apparently deliver more carbon to the sediments than do forams, for example.───举例来说，棘皮动物传送到海底的碳明显比有孔虫多。
As would be expected, a reduction in osmolality, however small, was observed when it rained on the exposed echinoderms.───就像被预计的那样，当下雨的时候，在棘皮动物身上都能观察到渗透压的降低，无论多小。
Echinoderms are now considered as a biological and geological model that underlies researches of primary importance.───棘皮动物现在被认为是生物和地质模型，头等重要的基础研究。
In addition, echinoderms, brittle stars seabed habitats of the body also detected radioactive cesium-137.───此外，海底栖息的棘皮动物海蛇尾的体内也检测出放射性铯-137。
Though they are commonly called starfish, these animals are not fish at all. They are echinoderms, closely related to sea urchins.───虽然它们通常被称为海星，这些动物不是鱼，它们是棘皮动物，与海胆密切相关。

Any of various cucumber-shaped echinoderms of the class Holothuroidea, having a flexible body with tentacles surrounding the mouth.
Many echinoderms such as starfishes and sea urchins also do this.
Echinoderms, like starfish, urchins and sea-cucumbers can be found here.
The echinoderms may seem, from a human point of view, to be a blind alley of no particular importance.
Any of various thin, circular echinoderms of the class Echinoidea, especially Echinarachnius parma, of sandy ocean bottoms of the northern Atlantic and Pacific.
Most echinoderms also have an unique five-rayed radial symmetry in the overall shape of the skeleton.
Unfortunately they feed exclusively upon live echinoderms attacking starfishes and sea urchins and can not be acclimatised to substitute foods.
Starfish, the most easily recognisable of the echinoderms have in addition evolved a further reproduction strategy.
Shells of molluscs, crustaceans or echinoderms and cuttle-bone, unworked or simply prepared but not cut to shape.
