Question
Chapter 21.8, Problem 1MC
Summary Introduction
To determine:
The number of arthropods that scientists have identified and mention the sub phylum with richest diversity of species.
Concept introduction:
Arthropods are included under the largest clade characterized by bilateral symmetry and three germ layers. Arthropods are protostomes that means mouth develops from the first opening in the embryo. The characteristic feature of arthropods is the presence of exoskeleton and joint paired appendages.
