Q.
Radial symmetry is NOT found in adults of phylum ______.
- A
Ctenophora
- B
Hemichordata
- C
Coelenterata
- D
Echinodermata
Solution
Adult hemichordates are bilaterally symmetrical. Ctenophores and coelenterates are radially symmetrical, and adult echinoderms display secondary pentamerous radial symmetry (their larvae are bilateral). So radial symmetry is absent in adult Hemichordata.
