this is a great article —Preceding unsigned comment added by (talk) 01:48, 21 August 2008 (UTC)

I believe that the picture of this article could be better as it does not give a very good picture of the most charactestic thing i.e. the head-shape —Preceding unsigned comment added by (talk) 16:00, 23 March 2011 (UTC)

Thanks for the article, any chance of inserting pics of male & female to illustrate the unusual sexual dimorphism if obtainable? (The 'plan view' photo included is pretty good by the way, maybe this could be identified as a male or female?)— Preceding unsigned comment added by (talk) 22:18, 6 November 2012 (UTC)

Cerebrospinal Fluid[edit]

I find that this article has an issue with citation in general, but I sadly don't know enough about sharks/shark resources to add anything beneficial. I do want to make at least a temporary adjustment to the statement about cerebrospinal fluid. Firstly, the combination of the words "special fluid" and cerebrospinal fluid being in quotations gives the impression that CSF is unique to these sharks... it is not. As far as I know, most vertebrates' brains float in the stuff, including humans. What seems to be unique is the type (that is, "CI-excess"). However, a very limited google search for "CI-excess" turned up a connection to bonnethead sharks -- on the 6th page of search results. I'm not saying the info is bad (at least one bonnethead shark website says "little is known about the cerebrospinal fluid", which is likely why it is so seemingly difficult to verify easily); but it does disturb me that a solid chunk of the results I found use the exact same wording as this Wikipedia article, and several of them seem to link to each other (and back to Wikipedia). Those that aren't word for word copies of this article rarely seem to use the term "CI-excess". For now, I'm removing the reference to CI-excess until it can be vetted by someone who both knows more than I (not hard), and actually has the references to back it up (somewhat harder).
