Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.
The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.
Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

Answer:
A very short history of climate change research. The story of scientists discovering climate change is longer than many of us tend to imagine.
We’ve had a sense that what humans do might effect the climate since Antiquity.
The aggregate (collective) of plants and plantlike organisms in plankton.
