What is the basis of classification in non chordates?
The general characteristic features of Non-Chordates are: They are cylindrical, triploblastic, coelomate, or pseudocoelomate animals. Respiration in these animals takes place through gills, trachea or body surface. Most of the times, sexes cannot be distinguished among the members.

What are the difference between chordates and non chordates?
The major point to differentiate between chordates and non-chordates is that chordates have a spinal cord or backbone in their body structure whereas non-chordates are without backbone or notochord in their body structure.

Which is group of animals has a notochord?
Chordata is a phylum (group) of animals which have a notochord. The group includes vertebrates, with some closely related invertebrates . Note: Lines show likely evolutionary relationships.
Are there any extinct taxa in the chordate family?
There are also extinct taxa such as the Vetulicolia. Hemichordata (which includes the acorn worms) has been presented as a fourth chordate subphylum, but now is treated as a separate phylum: hemichordates and Echinodermata form the Ambulacraria, the sister phylum of the Chordates.
Where does the origin of chordates come from?
According to a long-standing theory, the origin of chordates may be found in transformed larvae of sea-squirts ( tunicates ). Adult tunicates are sessile, but their larvae are motile, and have some features found in early vertebrates.
