虽然它可能是一个更广泛的节肢动物类的类形，但甲壳纲总纲的一个特征是拥有一个无节幼体，带有三对功能性附属物，触角，触角和下颚。无节幼体在所有甲壳纲中都表现出基本相同的组织结构，在无节幼体后期，在头节及其五个附属物的形成过程中，甲壳纲形态的巨大多样性首次变得明显。头部化是驱动甲壳类动物进化和多样化的一个关键引擎，而下颌后肢的特化形成头部进食器官的一部分是这一过程的一个主要部分（Walossek，1993年）。经典的比较解剖学揭示了大量关于甲壳纲动物上颌骨、上颌骨和上颌骨足（=第一胸足动物）肌肉组织的新数据（Boxshall和Huys，1992年）。
Although it may have been plesiomorphic to a wider group of arthropods, one characteristic of the superclass Crustacea is the possession of a nauplius larva bearing three pairs of functional appendages, antennules, antennae and mandibles. The nauplius larva exhibits basically the same organization across the range of crustacean classes in which it is retained, and it is in the immediate postnaupliar phase, during the formation of the cephalon with its complement of five appendages, that the great diversity of crustacean form first becomes apparent. Cephalization has been a key engine driving crustacean evolution and diversification, and the specialization of the postmandibular limbs to form part of the cephalic feeding apparatus has been a major part of the process (Walossek, 1993). Classical comparative anatomy has revealed a wealth of new data concerning the musculature of the maxillules, maxillae and maxillipeds (= first thoracopods) in the Crustacea (Boxshall and Huys, 1992).
