[edit] Original research

Firstly the article needs to establish that it is not original research. Then, some questions (and remember I know only what I've read here):

• The "vertical force" from the surface layer is presumably counteracting the weight i.e. acting vertically upwards, right? Or have I missed something? answered
• What is a "contact perimeter"?
• There is an implicit statement that this page is only upon creatures where mg/(σP) < 1. Is this true? If so, need to be explicit. answered Sliggy
• Does the next paragraph repeat itself over the two sentences? Is there a word missing?
• The fact about the Gigantametro Gigas is interesting, but could we have some other data points for comparison? Otherwise it's just a random number. Whoo-hoo, but meaningless. Also, any reason why their legs get longer as they get bigger?
• The description of thrust generation sounds more like a mass transferrence (grab a bucket of water and chuck it backwards). Maybe a diagram might help? Or a re-write (eg filaments of what? Hair?)
• The water deformation via body posture definitely needs a diagram. I can picture the meniscus, but not how the heck it is deformed to surf on to dry land.
• I don't really see a solution to Denny's paradox in this article, or is it because I am ignorant of the subject and simply didn't notice it?It's in water strider. Doh. Sliggy

Just some random questions. Sliggy 22:59, 4 January 2006 (UTC)

[edit] AfD

This article survived an AfD. The discussion is here. enochlau (talk) 23:22, 10 January 2006 (UTC)

[edit] trimmed verbiage

(in m g (where m equals the mass of the animal and g the gravitational acceleration) σP (where σ equals the surface tension and P equals the contact perimeter of the animal's feet).

[edit] Broader article?

How about something like life on the surface of water. This could summarize this more specific article. Richard001 (talk) 08:16, 6 February 2008 (UTC)
