A picture of a sea spider would really go a long way to making the text of this article much clearer, but the only picture of a sea spider I've ever seen (which made this clear to me) is a drawing in Fingerman's Animal Diversity textbook, and the drawing is copyright-encumbered. If you've got access to an image of a sea spider that isn't so encumbered, please put it up here. --arkuat (talk) 06:28, 16 August 2005 (UTC)

[edit] most divergent of arthropods?

Take a look at a free summary from Science [1]:

Sea spiders do seem to be as primitive as they look. Unlike spider fangs, both chelifores and their nerves sprout from the cells that form the front most part of sea spiders' brains, the team reports 19 October in Nature. This supports the theory that sea spiders belong to their own ancient lineage that predates the origin of all other modern arthropods. It also suggests that all of today's other arthropods inherited their heads from a subsequent ancestor that gave up such up-front appendages.

[edit] No coelom?

I read somewhere that the sea spiders don't have any coelom. Is this correct?

"Pycnogonids possessed a coelom at one point, but it was eventually lost through evolution". IronChris | (talk) 20:50, 22 August 2006 (UTC)

[edit] Do they or don't they?

The article contradicts itself: "Sea spiders do not swim but rather walk along the bottom with their stilt-like legs." Then in the next paragraph: "They crawl slowly along (although some do swim), feeding." I'm no expert, but both cannot be true. RandyKaelber 20:51, 22 September 2006 (UTC)
