Protostomes. Development begins with spiral, determinate cleavage. Coelom formation then begins in the gastrula stage, the coelom forming from splits in the mesoderm. The mouth then develops from the first opening, the blastopore, and the anus develops secondarily.

∙ 12y agodeutorsomes because the initial opening will become the mouth, for instance annelids, or arthropods, Spiders, but in deutorsomes the opening will become the anus,your butt,,
Correction:
A deutrosomes's initial opening is the ANUS NOT the mouth.
Protosomes first opening is the mouth.

Is a rat a protostome or deuterostome?
A pig is a deuterostome like all other mammals. This means that the anus and mouth are present during embryogenesis.
Are fish triploblastic?
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
Coelomates that develop with the blastopore becoming the mouth are?
Coelomates that develop with the blastopore becoming the mouth are protostomes. An example of a protostome would be the Caribbean reef squid.

protosome
Pigeons deuterostome or protostome?
deuterostomes
Are planarians deuterostome?
They are neither a deuterostome or a protostome, since they only have one opening.
At which developmental stage should I be able to distinguish a protostome embryo from a deuterostome embryo?
Gastrulation

Is porifera a protostome or deuterostome?
deuterostome ^This is actually false porifera are not segmented animals so thay don't form mouth first(Protostones) or butt first (Deuterostomes) so they are under developed being N/a
What does proto and deutero?
Protostome means the blastopore becomes the mouth during embryonic development, and deuterostome, the anus. We're deuterostomes.

What does the blastopore become?
At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes
Is a green sea turtle a cephalopod?
Nope. They are reptiles. Cephalopods are octopuses and squids and cuttlefish. Reptiles and cephalopods are not very closely related at all; cephalopods are protostomes and cephalopods are deuterostomes, and the protostome/deuterostome split occurred very early in the history of animalia.
Are humans deuterostome?
Deuterostome. Anus is formed first.
Is a star fish a deuterostome?
During embryonic development, a deuterostome's first opening is its anus rather than its mouth. Starfish are a type of phylum that is classified as a deuterostome.
