The Animal Kingdom
动物界
Though there is great diversity in the animal kingdom, animals can be distinguished from the other kingdoms by a set of characteristics. Though other types of life may share some of these characteristics, the set of characteristics as a whole provide a distinction from the other kingdoms. The set of characteristics provided by Audesirk and Audesirk are:
尽管动物界种类繁多，动物可以凭借一组特征与其他界别区分开来。尽管其他类型的生物可能共享一些这些特征，但这些特征的集合整体上能够区分动物与其他界别。Audesirk和Audesirk提供的特征集为：
- Animals are multicellular.
动物是多细胞的。 - Animals are heterotrophic, obtaining their energy by consuming energy-releasing food substances.
动物是异养的，通过消耗释放能量的物质来获取能量。 - Animals typically reproduce sexually.
动物通常进行有性繁殖。 - Animals are made up of cells that do not have cell walls.

动物能够迅速对外部刺激作出反应，这是由于神经细胞、肌肉或收缩组织，或两者共同作用的结果。
