Question

Which of the chordate characteristics do tunicates retain as adults?

Answer 1

The characteristics used during larva stage are:- 

1.) A notochord,

2.) A dorsal hollow nerve cord,

3.) Pharyngeal slits,

4.) A post-anal tail. 


In adult stage it uses:- 

1.) The notochord,
 
2.) Nerve cord, 
 
4.) Tail disappear.

Answer 2

Tunicate Chordate Subphylum

Explanation:

• The larval stage of the tunicate has all the highlights normal for chordates, pharyngeal cuts and a post-anal tail,a dorsal empty string and a notochord
• In the grown-up arrange the notochord, nerve rope, and tail disappear  
• Urochordata (tunicates) and Cephalochordata (lancelets) are invertebrates because they lack a backone
• Larval tunicates (Urochordata) gangs each of the four structures that group chordates, yet grown-up tunicates hold just pharyngeal slits  
• The larva metamorphoses into a grown-up, the tail resorbs, giving food stores to the developing animal. Free-swimming tunicates transform without attachment
