WikiProject Animals To-do:

It seems to me that these critters have endostyles that eventually give rise to the mammalian thyroid gland. Shouldn't this be mentioned somewhere in the lead article?

Do lancelets have eyes? If no, when did they start evolving in chordates (probably in platyhelminthes I guess)?PhoenixSeraph 22:13, 1 April 2006 (UTC)

  • They have only one pigment spot on their front end which detects light.

hey, people help me translate description for image. -PioM22:55, 14 Jun 2005 (UTC)

[edit] Commercial use

In Asia, they are harvested commercially. -- what for? Food? If so, what sort of food? --Spudtater 00:31, 21 February 2006 (UTC)

Yes, for food. Both for humans and animals. I wonder how it tastes. Would like to try it made in the same way as fish and chips.

"Today, amphioxus may be extremely common in shallow sandy environments: at Discovery Bay, Jamaica, up to five thousand individuals per square meter of sand have been reported. In some parts of the world, amphioxus are eaten by humans or by domestic animals; they are important food items in some parts of Asia, where they are commercially harvested."

From American Scientist :
"Lancelets in a bay near Xiamen, China, evidently supported a fishery for at least a few hundred years. The muscular animals were either eaten fresh (they taste like herring) or were dehydrated by roasting in a little oil and used as an additive for other dishes."
If they taste like herring, they doesn't taste bad at all. 193.217.193.154 17:54, 15 July 2007 (UTC)

[edit] Humans ?

Look at this :

"In common with the vertebrates, lancelets have a nerve cord running along the back, pharyngeal gill slits and a tail that runs past the anus. Also like humans, the muscles are arranged in blocks called myomeres. Unlike the vertebrates, however, ..."

Why "humans" ? Only humans and lancelets do have myomeres, really ?
What about other vertebrates between them ?
They are trying to emphasize that humans came from Lancelets. And they did.

[edit] Subphylum relationships within the Chordata

The major "textbook view" of Chordate subphylum relationships places the lancelets as a sister-group to the vertebrates. This is the picture presented in cladograms by both Brusca & Brusca (Invertebrates, Sinauer Associates 2003) and Miller & Harley (Zoology, McGraw-Hill 2007), as well as the Three of life project. This wikipedia article, however, appears very biased in expressing the other view, which is placing Urochordates as a basal group.

Stating neutrality as a goal, wikipedia articles should try not to take stands in ongoing debates. I have seen the "newer research suggests that" argument used in advocacy of both of the vertebrate sistergroup views; it is thus not very convincing unless one also states what kind of evidence there is for either view.--Gunnar Mikalsen Kvifte (talk) 06:58, 20 December 2007 (UTC)

[edit] lancelets in music ¿?¿?

I find the section completely off-topic. It is only anecdotal and lacks sources. —Preceding unsigned comment added by Angelpeream (talk • contribs) 09:09, 24 April 2008 (UTC)

[edit] Images

You can use this ( lancelet) excellent image for your article ^___^. Also you can translate the article about amphioxus from Russian Wikipedia --LameClock (talk) 11:18, 4 June 2008 (UTC)
