Starfish are not single celled organisms. Starfish are actually quite complex organisms with the ability to recreate due to their sophisticated organization of cells.
No, starfish are deuterostomes. They belong to a group of animals where the blastopore becomes the anus during embryonic development. This is opposed to protostomes, where the blastopore becomes the mouth.
No. They are a multi-celled organisim just like you and me and cows.

Why are crayfish classified as protostomes?
Crayfish are classified as protostomes because they are a type of invertebrate animal that develops their mouth before their anus during embryonic development. This characteristic is a key feature of protostomes, which also includes other invertebrates like insects and mollusks.
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.
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 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 protostomers and deuterostomers is based on differences in their what?
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.
Are mammalia deuterostomes?
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Are flatworms prokaryote or eukaryote?
They are protostomes.
Are worms protostomes?
Most invertebrate animals are protostomes.
Are leeches protostomes?
Yes, since they are annelids, they are protostomes.
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.
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 bivalves protosomes or deuterostomes?
Protostomes .
What is the animal if the blastopore develops into a mouth?
protostomes:)
How many times have wings for powered flight evolved in protostomes?
Wings for powered flight have evolved multiple times in protostomes, with the best-known example being in insects. Other protostomes that have evolved wings for powered flight include some groups of arthropods, such as butterflies and dragonflies.
Why are crayfish classified as protostomes?
Crayfish are classified as protostomes because they are a type of invertebrate animal that develops their mouth before their anus during embryonic development. This characteristic is a key feature of protostomes, which also includes other invertebrates like insects and mollusks.
Are cnidarians protostomes or deuterostomes?
Although most of the animal phyla are included in the deuterostomes and protostomes, cnidaria, porifera, placozoa and ctenophora are not included in the group of animals know as Bilateria (which contains the deuterostomes and protostomes). Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa.
