Starfish are not single celled organisms. Starfish are actually quite complex organisms with the ability to recreate due to their sophisticated organization of cells.

What features define the group Lophotrochozoa?
Protostomes
Why are crayfish classified as protostomes?
They have remote nipples, that are used for warmth.
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?
embryological development
Which adaptation is unique to insects among all protostomes?
The ability to move by flying
Are mammalia deuterostomes?
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Are flatworms prokaryote or eukaryote?
They are protostomes.
Are bivalves protostomes or deuterostomes?
protostomes
Are worms protostomes?
Most invertebrate animals are protostomes.
Are leeches protostomes?
Yes, since they are annelids, they are protostomes.
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.
What features define the group Lophotrochozoa?
Protostomes
Are bivalves protosomes or deuterostomes?
Protostomes .
What is the animal if the blastopore develops into a mouth?
protostomes:)
Are annelids bilateral?
No, they are protostomes. Protostomes form their mouth first in their embryonic development (it also means ´mouth first´). Deuterostomes form their anus first, and their name means ´mouth second´. Deuterostomes include echinoderms such as starfish and sea urchins, and us chordates including the vertebrates. Everything else, save for sponges and jellyfish, is a protostome.
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.
