Deuterostome. Anus is formed first.
Yes, a protostome is, and so is a deuterostome. Neither are diploblastic. This is mainly because of the developement of the coelem or body cavity. Just remember, both protosome and deuterostome require a three germ layer (that is a triploblastic cell) - ALWAYS
Protostome example: Arthropoda (insects, spiders) Deuterostome example: Chordata (vertebrates, including mammals, birds, and fish)
