Intro: Ectotherm

Is a hydrostat really particularly common for ectothermic -- 'cold blooded' -- organisms? Is there a reference for this? Seems like a lot of ectotherms don't have a hydrostat... Everybody knows this is nowhere (talk) 20:06, 23 January 2016 (UTC)[reply]

Fixed. While they are ectotherms, that's not really relevant to the topic, so I deleted it. HCA (talk) 15:42, 8 February 2016 (UTC)[reply]

Penis

The Diane Kelly "discovery" feels like self-promotion and takes up an over-proportional amount of space in this short article. I would even argue that this is a fringe opinion in Biology and the penis is not a exoskeleton in the actual sense. I feel it should be deleted from this article. 159.230.248.39 (talk) 23:55, 1 September 2015 (UTC)[reply]

Well, there's no evidence of self-promotion; the user who added it seems to have just pulled it from a TED talk. The length of this section isn't a problem in absolute terms; it merely looks long because the article is so short. And nobody says it's an exoskeleton, only that it's a hydrostatic structure and could be considered a form of skeletal element; after all, we say the same about the notochord, which is also hydrostatic and persists into adulthood in some species.
