There is ‘stomochord’ present which is similar to the notochord. Also, a dorsal nerve chord is present in addition to small ventral nerve chord.

Hemichordates have notochord in their embryonic stage but as they grow it disappears. Therefore we can conclude that they show retrogessive development in context to notochord
