Answer:
They are generally found in marine water.
Their body is bilaterally symmetrical, triploblastic, and coelomated.
At a certain stage of their lives, their body develops a long, rod-like structure for support called notochord.
They exhibit organ system level of organization.
Eg., Herdmania, Amphioxus.
