urochorda การใช้

• In 1881, Francis Maitland Balfour introduced a second name for the same group, " Urochorda ", to emphasize the affinity of the group to other chordates.
• Accordingly, the current ( formally correct ) trend is to abandon the name Urochorda or Urochordata in favour of the original Tunicata, and the name Tunicata is almost invariably used in modern scientific works.
