Answer 2

Balanoglossus is considered as a link which connects the chordates and non chordates.

It is because though Balanoglossus is a non chordate but still they have some characters of chordates like - possessing a notochord, a nerve cord which is tubular in shape, and also the gill slits.

Because of this reason Balanoglossus is regarded as the connecting link between them.
