Summary Introduction
Concept introduction: Arthropods are considered as the biologically most successful animal group. The arthropods are more diverse group of animals and they cover a greater range of habitats than the other animal group members. According to various molecular data, eye structure, and genome analysis, the pancrustaceans are divided into two groups, namely crustaceans and hexapods (insects).
