Answer:
Urochordata
Explanation:
Chordata is an animal phylum characterized by four features at some point in their lifetime. These four features are:
- notochord
- pharyngeal slits
- dorsal hollow nerve cord
- post-anall tail
Chordata is further divided into urochordata, cephalochordata and vertebrates.
Urochordates display all the four features of chordates in their larval form but their adult form has none of them except pharyngeal slits. They also change from their free swimming larval form to sessile adult form which means that they attach to a surface unlike the larval form. They also display filter feeding i.e. their food is filtered via the pharyngeal slits. Since all these characteristics are being displayed by the newly discovered species, it belongs to urochordata group.
