Members of this phylum are marine worms less than 1mm long. They have no body cavity but do have a pair of jaws which gives them their name (gnathos is Greek for jaws) and a blind gut with a mouth but no anus. They are very common in marine sediments where they eat bacteria, fungi and protists, and there are about 80 known species.
