Q.
Which of the following is a connecting link between
invertebrates and non-invertebrates?
Animal Kingdom
Solution:
Balanoglossus is a connecting link between invertebrates
and non-invertebrates. Balanoglossus belongs to phylum
Hemichordata which was earlier considered as a sub-phylum
under phylum chordata. But, now it is placed as a separate
phylum under non-chordata because notochord and post-anal
tail are absent in it.
