Web links for taxonomy[edit]

There are separate web links listed for the Margulis & Schwartz classification and Cavalier-Smith's classification, but the two links are identical. Also the link associated with Cavalier-Smith refers to him as Cavalier-Jones. Is there a reason for this? Cephal-odd 17:00, 25 November 2006 (UTC)

The different classification schemes in the Taxonomicon are tabs on the page, and you can only link to the page, not the individual tabs. I added a bit instruction to the links on how to find the classifications. As for the name, it looks like a typo (that I may have made last year). The Taxonomicon does list him as Cavalier-Smith. -- Donald Albury 18:52, 25 November 2006 (UTC)
Thanks for pointing out the different tabs on the Taxonomicon. I didn't realize the website had that feature. Cheers, Cephal-odd 04:44, 27 December 2006 (UTC)

Tail fin for propulsion[edit]

"Chaetognaths swim using their tail fin for propulsion" can anybody cite a source for this statement? I have found information to the contrary "Tail fin is...with no musculature and therefore incapable of swimming movements."Phylum Chaetognatha: Wesley R. Elsberry although I'm not certain of the reliability of this source. 07:01, 3 May 2007 (UTC)

Ray fins[edit]

"Unlike those of vertebrates, however, these are composed of a thickened basement membrane extending from the epidermis"

This distinction would be more useful if someone could explain how they are unlike ray fins in fish, whose composition is not described either here or on the fin ray section. The latter gives some general traits of rays and spines, but no technical information, followed by a description of Lepidotrichia. It's obviously a slightly tricky area because it's not strictly either page's responsibility to describe the other one, but it leaves statements like this that lead off into thin air. -- Shimmin Beg (talk) 10:03, 17 February 2013 (UTC)
