Herdmania has a freely swimming larva whose notochord is restricted to the tail region. This places it in which subphylum?
AHemichordata
BCephalochordata
CVertebrata
DUrochordata
Answer & Solution
Correct answer: D. Urochordata
1. The notochord lies only in the tail of a free-swimming larva.
2. 'Uro' means tail, so this is subphylum Urochordata.
3. Rule out Cephalochordata: there the notochord runs the whole body length.
4. In Hemichordata the notochord is in the proboscis, not the tail.
