The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.

Notochord
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as?
The elaboration of a notochord and a dorsal nerve chord the key developmental event that marks the evolution of the chordates is referred to as neurulation. The hollow crater formed during gastrulation is known as the archenteron.
What character is unique to chordates?

Is an animal with a backbone and gills but no notochord still a chordate?
No, an animal with a backbone and gills but no notochord would not be considered a chordate. Chordates are defined by the presence of a notochord at some stage of their development, along with a dorsal nerve cord, pharyngeal slits, and a post-anal tail.
What is the definition of notochord?
Notochord- a flexible rod that supports a chordates back.notochord is a stuff rod of conective tissue.it is present in the mid_dorsal region of the embryo.in the lower chordates .the notochord is present throughout of life but in vertebrates .the vertebral column or bacjbone replaces it.
What is the flexible supporting structure found only in chordates?
The flexible, supporting structure found only in chordates is called the notochord. The notochord is located between the nerve cord and the digestive track.
Which animals are chordates and craniates but not vertabrates?
Hagfish are chordates and craniates, but they are not vertebrates. This is because they have a skull and notochord but lack vertebrae.
Is chordates vertebrates?
Chordates are not vertebrates because although some vertebrates are chordates theres many reasons why chordates arent vertebrates.the first reason is because chordates consist of a notochord or a dorsal nerve.
All chordates have a supportive rod along their back called the?
notochord
Do tunicates and lanceletes have back bones?
No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.
What distinguishes a chordates?
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
