Which of the following is not a characteristic of chordates?
- A.Presence of notochord
- B.Central nervous system is dorsal
- C.Absence of gills✓
- D.Presence of post-anal part (tail)
Correct Answer
(C) Absence of gills
Solution & Explanation
Chordates possess (at some stage) a notochord, a dorsal hollow nerve cord, a pharynx perforated by gill slits, a ventral heart and a post-anal tail. Presence (not absence) of pharyngeal gill slits is a chordate feature, so 'absence of gills' is NOT a chordate characteristic.
