2. Notochord is a supporting structure, part of internal skeleton found only in chordates. Nervecord is part of nervous system, mesodermal in origin and is found in both chordates and non-chordates. Notochord is formed on dorsal side in chordate while nerve cord is ventral in non-chordates and dorsal in chordates. Earthworm belong to phylum annelid, i.e. non-chordate. So earthworm does not have notochord and nerve cord is ventral in position.
