Balanoglossus is considered as a connecting link between chordates and non-chordates.

• A. True
• B. False

Answer 1

The correct option is A True

Any animal that shows characteristics of two different groups of animals is considered to be the connecting link between the two groups.
Balanoglossus is considered as a connecting link between chordates and non-chordates as it shows characteristics of both phylums. For example, it shows the presence of notochord and pharangeal gill slits which is a characteristic of chordates. It also shows the presence of heart which is dorsal just like non-chordates.
