| Answer» Balanoglossus\xa0is a deuterostome, and resembles the Ascidians or sea squirts, in that it possesses branchial openings, or "gill slits". It has notochord in the upper part of the body and has no nerve chord. It does have a stomochord, however, which is gut chord within the collar.\xa0Balanoglossus\xa0is an ocean-dwelling acorn worm (Enteropneusta) genus of great zoological interest because, being a\xa0Hemichordate, it is an "evolutionary link" between invertebrates and vertebrates. ... Hyman (1959), however,\xa0placed\xa0them near Echinodermata and gave\xa0Hemichordata\xa0a status of an independent\xa0phylum. | |
