Abstract
The Arthropoda are animals with chitinous exoskeletons and jointed appendages, and they moult to grow. They have no cilia at any time during their development. Because most arthropods have segmented bodies, the group is frequently regarded as having evolved from annelids or preannelids (e.g., Fig. 3.1). The similarities, however, are confined to the adults; the larvae are markedly dissimilar. In its broadest interpretation, the Arthropoda comprises the Tardi-grada, Pentastoma, Chelicerata (including arachnids), Crustacea, Uniramia (including insects) and, problematically, Onychophora. Onychophorans have cilia, and the main reason for their inclusion in the Arthropoda is their similarity to insect caterpillars. I shall here consider the larvae of crustaceans and some insects.
