at the intent that the title eventually be changed to All the crap i can find about any marine worm.
With some refs, tho, it might be good to list the phyla (or even lower taxa) that include only marine worms. I think the polychaetes (an annelid class) are an example.
The "blood vessels" bit is not total nonsense (altho (blood) veins are a subset of blood vessels -- and bluish BTW rather than red like the up end of giant tube worms), but find a ref and and produce from it a paraphrase that uses encyclopedic language.
