What are prechordates?

Answer 1

Answer:

Protochordates are an informal category of animals (i.e.: not a proper taxonomic group), named mainly for convenience to describe invertebrate animals that are closely related to vertebrates. This group is composed of the Phylum Hemichordata and the Subphyla Urochordata and Cephalochordata.

This means that, during the embryo development stage, the anus forms before the mouth. All chordates are based on a bilateral body plan.
