sessile animals

基本解释

The sessile salamander-like animals had the unique ability to "push back" the Force, creating areas wherein use of the Force was impossible.
这种蝾螈类固着动物拥有“排开”原力的特殊本领，它们能创造出一块块无法使用原力的区域。
This is serious because such sessile creatures are not merely part of the ecosystem. In a sense, they are the ecosystem—in the way that it is plants rather than animals that define a forest.
这种损害是十分严重的，因为这些固定生长的生物不仅仅是生态系统的一个环节，某种意义上，它们本身就是生态系统——森林生态系统是根据其中的植被而不是动物来定义的。
This is serious because such sessile creatures are not merely part of the ecosystem. In a sense, they are the ecosystem—in the way that it is plants rather than animals that define a forest.
认真说来，这些固着动物不仅仅是生态系统的部分，一定意义上，他是森林一样的提供居住环境的生态系统，以植物生态系统的方式存在，而不是动物。
