Why are hemichordate not considered as proper chordate?
Hemichordates are not considered true chordates because they lack several key characteristics that define the phylum Chordata. While they possess a structure called a stomochord, which is somewhat analogous to the notochord in chordates, they do not have a true notochord. Additionally, hemichordates lack other critical features such as a dorsal nerve cord and pharyngeal slits that are characteristic of chordates. Thus, despite some similarities, hemichordates are classified in a separate phylum due to these fundamental differences.
What symmetry are the phylum hemichordata?
Adult Hemichordates exhibit bilateral symmetry, meaning their bodies can be divided into two similar halves along a single plane. However, during their larval stage, some species of Hemichordates show a form of metameric or radial symmetry.
