The early stages of chordate development show features shared with some invertebrate phyla, especially the mouth that forms separately from the anus, as it does in the phyla Hemichordata , Echinodermata , and Chaetognatha .
A chordate ( / ˈkɔːrdeɪt / KOR-dayt) is a deuterostomic animal belonging to the phylum Chordata ( / kɔːrˈdeɪtə / kor-DAY-tə ). All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics ( synapomorphies) that distinguish them from other taxa.
