message: Annelids? Has anyone since 1960s seriously thought these were annelids? Their embryology is clearly that of Deuterostomia, AFAIK, so they cannot be protostomes like annelids. Can anyone sort this out?—Preceding unsigned comment added by 89.139.66.39 (talk) 13:00, 24 February 2007

message: I've heard they live for over 300 years growing a quarter of an inch a year. Can anyone find a source for this?--Wowaconia 04:04, 15 February 2007 (UTC)

message: The article says that they evolved this way because they live so deep. Isn't it more likely they live so deep because they evolved that way? Obviously they'd have to become extremophilic before they could survive in that environment, and considering which one is the faster process...
Not that I believe in such things, of course.  —Preceding unsigned comment added by 64.122.63.142 (talk) 17:07, 2 April 2008 (UTC)

message: I stripped this out of what is now Tube worm (body plan):
: It may also refer to the bright red worms found living at the bottom of the ocean near active sulfur vents. These worms live in huge colonies clumped together around the hydrothermal vents.
If i don't get around to checking that all of it duplicates the accompanying article, could someone do so, and note below that it's done, or unsuitable? --Jerzy•t 04:03, 2 December 2009 (UTC)

message: Taking in account that earth is 4.5 billion years old and the hydrothermal underwater vents won't be far just say 4 billion years old, is it possible that these worms and other species living in this environment are about 4 billion years old as well? Which could possible make it the oldest living life form in the world? 206.83.103.20 (talk) 18:47, 21 December 2022 (UTC)
