The phylum is Annelida. I believe the word comes from Latin and the Latin word means "little ring". I suppose this is referring to the small ring shapes segmented worms are made up of.
it is Phylum Annelida.
Annelids are segmented worms, such as Earthworms. See the link below for a fuller description.
If you mean parasitic flatworms, they belong to the phylum Platyhelminthes.
If you mean coral, it belongs to the phylum Cnidaria.
If you mean kingdom like domain, phylum, and class then the kingdom is Animalia.
No, they belong to the family phylum chordate which mean they have a spinal cord/vertebrae
If by largest you mean greatest biomass then it would have to be the round worms phylum Nematoda if you mean the greatest number of species then it would have to be anthropoda as it includes the insects. If you mean by size then it would have to Chordata as it includes the whales. If by largest you mean greatest biomass then it would have to be the round worms phylum Nematoda if you mean the greatest number of species then it would have to be anthropoda as it includes the insects.

Porifera is a phylum, not a kingdom, but I assume you mean the phylum in the kingdom Animalia. According to wikipedia, there are about 5000 different species in Porifera.
Perhaps you mean Nematode. If so then it's a round worm similar to earth worms. There are several differences the most obvious being they are not segmented like earth worms. You can find more info here: http://en.wikipedia.org/wiki/Nematode
If by biological you mean the phylogeny it's phylum mollusca, class bivalvia, subclass heterodonta
..."answer it?", you mean, "no one is alive who has answered it"?...
if you mean nephridia (an extra 'i' second to end) they are specialised organs that function similar to kidneys in that they are used for osmoregulation and excretion. In annelids (which are segmented worms) there is one pair of nephridia per segment.
this is in my science h.w today too lol...I found out it's called ANNELIDA!!! but if ya know im trying to figure out the answer to a worms common name for phylum!!! if ya know let meh know...thnxxx yo
