Summary Introduction
To list: The major clades of protostomes and identify their distinguishing characteristics.
Introduction: Bilateriansare the animals with bilateral symmetry, which means that the left and right sides of the embryo are mirror images. The bilateral symmetry allowed these animals to achieve high levels of specialization within parts of their bodies such as the concentration of sensory structures at the anterior phores.
