Vedclass · Answer

(A) $Urochordata$ (also known as Tunicata) belongs to the subphylum of Chordata.$1$. They are chordates,but the notochord is present only in the larval tail.$2$. They are triploblastic and coelomate animals,not pseudocoelomates.$3$. They are invertebrates,not vertebrates,because they lack a vertebral column.Therefore,the statements 'They are vertebrates' and 'They are pseudocoelomates' are incorrect. However,in the context of typical multiple-choice questions,the most fundamental error regarding their classification is that they are not vertebrates.

$(1)$ Notochord present only in larval stage.	$(a)$ Chordata
$(2)$ Notochord present throughout life.	$(b)$ Vertebrata
$(3)$ Notochord is replaced by vertebral column.	$(c)$ Cephalochordata
$(4)$ Notochord is mesodermal in origin.	$(d)$ Urochordata

Which of the following is incorrect for $Urochordata$?
