I just read this page for the first time. Saying that dorsal fins are infamous seems somewhat biased. Also there are a lot of sentence fragments, and other grammatical errors that make the last paragraph difficult to understand. I am not a serious editor, but someone should work to clean up this page. 70.127.68.125 (talk) 17:42, 21 February 2009 (UTC) JAHIIIWolf (non member).
- I think it reads fine, now. I don't really see a problem with that mention of the "infamous dorsal sign". --Swift (talk) 22:53, 30 December 2009 (UTC)
What about discussing the material(s) that comprise dorsal fins? What exactly are they made of? Throughout the internet I've come across a lot of references to "fibrous tissue" relative to marine mammals, but this seems a little vague. Also, I know that fish have bones/cartilaginous structures called "pterygiophores" that support their dorsal fins; do marine mammals have them too? Maybe an expert could elaborate on this? From what I can tell, the dorsal fins, pectoral fins and flukes of all marine mammals are made of the same material, so it might be advisable to create a new page, or perhaps link to an existing page? - Myrddin_Wyllt 9/18/2010
