Spider's legs

Do a spider's legs qualify as muscular hydrostats? Fluid pressure is involved in their movement, but they are covered in a rigid exoskeleton rather than being "tubes made of muscle". — Preceding unsigned comment added by 74.104.159.45 (talk) 08:16, 26 August 2011 (UTC)[reply]

I'm pretty sure they do not, and since it was unreferenced I went ahead and removed it. Augurar (talk) 10:54, 4 January 2012 (UTC)[reply]

Image

There's a photo now, but that person appears to have a curiously long tongue. Is that an unmanipulated photo? —Preceding unsigned comment added by 209.104.242.106 (talk) 19:29, 14 April 2008 (UTC)[reply]

The photo has not been manipulated (I'm just lucky). If you have any questions concerning the authenticity, you can contact me at raeschmied@hotmail.com —Preceding unsigned comment added by Venenodelalengua (talk • contribs) 06:46, 30 October 2010 (UTC)[reply]

Relation to hydrostatic skeleton

This article and the Hydrostatic skeleton article state that "muscular hydrostat" and "hydrostatic skeleton" refer to similar but distinct concepts. However, the article on the role of skin in locomotion states that a muscular hydrostat is a type of hydrostatic skeleton. Does anyone know which usage is correct or more commonly used? I'm not familiar with the relevant literature, myself. Augurar (talk) 10:44, 4 January 2012 (UTC)[reply]

In a sense, a muscular hydrostat is a type of hydrostatic skeleton. A hydrostatic skeleton is any system where structural support is provided by fluid pressure, including the fluid within a muscle. Muscular hydrostats are just a special case that crops up quite frequently. HCA (talk) 22:09, 15 January 2012 (UTC)[reply]

Is it a tentacle?

Can it be said that a human tongue is a tentacle? Are muscular hydrostats tentacles? Or are they structures which can be a _part_ of a tentacle? Ncr100 (talk) 20:15, 18 September 2014 (UTC)[reply]

Why does "pneumoskeleton" redirect here?

Not mentioned in article. What does it mean? 86.179.191.90 (talk) 01:20, 8 February 2015 (UTC)[reply]

You know, I'm not sure. I've never heard the term before. Could it be related to the pneumatophore of man-o-war siphonophores? HCA (talk) 01:26, 8 February 2015 (UTC)[reply]

helical fiber length

Near the end of the article, this sentence does not seem to make sense: "The length of the helical fiber is at a minimum when the fiber angle equals 54°44′ and is at maximum length when the fiber angle approaches 0° and 90°." If we consider the length of the helical fiber as a function of its crossing angle with respect to the longitudinal axis, surely this function has a minimum (not a maximum) at 0 or 90 degrees. Presumably the maximum of the function occurs at the indicated value of 54°44′. Moreover I checked the article cited for this sentence, and found nothing relevant to this question (though the article is quite interesting). — Preceding unsigned comment added by 100.34.171.34 (talk) 18:51, 10 March 2021 (UTC)[reply]
