Are the phylums Ctenophora or Platyhelminthes protostome or deuterostonme?

"They are neither. This is because they do not have a true gut. Protostomes are annelidids(earthworms) Mollusca(clams, snails, octopus, etc.) and arthropods which are your insects or spiders. The only Deuterostomes are Phlya Chordota and Echinodermata." The above answer is incorrect. Plathyhelminthes are protostomes. There are many, MANY groups of protostomes besides annelids, molluscs, and arthropods.


Is chaetognatha solidly advanced deuterostomes?

No, chaetognaths are not considered deuterostomes. They belong to the phylum Chaetognatha (arrow worms), which are classified as protostomes. They are characterized by certain developmental and anatomical features that distinguish them from deuterostomes.


Are cnidarians protostomes?

No, cnidarians are not protostomes. They are classified as diploblastic animals, meaning they have two germ layers during development (endoderm and ectoderm), whereas protostomes are triploblastic animals with three germ layers. Cnidarians are more closely related to animals like jellyfish, corals, and sea anemones.


The distinction between protostomes and deuterostomes is based on differences in their?

The distinction between protostomes and deuterostomes is based on differences in their embryonic development. Protostomes develop their mouth first from the blastopore, while deuterostomes develop their anus first from the blastopore. This difference in early development leads to distinct patterns of development in the two groups.


Are crayfish herbivore?

Crayfish are omnivores, meaning they are both an herbivore and a carnivore.

Are leeches protostomes?

Yes, since they are annelids, they are protostomes.


Are worms protostomes?

Most invertebrate animals are protostomes.


Why is the crayfish classified as a segment animal?

Its tail or abdomen is segmented


What two characteristics make a crayfish and arthropod?

Crayfish are classified as arthropods, because of their characteristic segmented bodies, chitinous exoskeleton, and joint appendages.


Are bivalves protostomes or deuterostomes?

Bivalves are protostomes. They belong to the phylum Mollusca, which is characterized by protostome development. This means that during their embryonic development, the blastopore becomes the mouth.


Why it is the crayfish is classified as a segmented animal?

A crayfish has segments, which are sections of a body that are separated by a crease, so it might be determined as segmented because it has only two so it may be classified but it might not. Worms have many segments.


Are Mollusks segmented worms and arthropods Protostomes?

Yes, molluscs fit into the group known as protostomes.


Are Chordates and echinoderms are both protostomes?

Neither are protostomes. Chordates, Hemichordates, and Echinoderms are all deuterostomes (in that the blastopore forms the anus first). In protostomes, the blastopore forms the mouth first.


Are planarians deuterostome?

They are neither a deuterostome or a protostome, since they only have one opening.
