What phylum do chordates belong to?

Chordates belong to the phylum Chordata, which is a diverse group of animals known for specific morphological features that define them. These include the presence of a notochord (a flexible, rod-like structure that provides support), a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some stage in their life cycle.

This phylum includes a wide range of organisms, from simple fish to more complex mammals, and encompasses important characteristics that are significant in the study of evolution and biology. The diversity within Chordata highlights the evolutionary advancements that allow for increased complexity in structure and function among vertebrates and some closely related invertebrates.

Understanding the defining features of Chordata allows for a greater appreciation of the evolutionary relationships among various life forms and the biological processes that contribute to their adaptation and survival in various environments.
