Talk:Sleep in animals

message: In herbivores, an inverse correlation is apparent between body mass and sleep length; big animals sleep more than smaller ones.
Ok I'm not an expert here, but this makes no sense to me. Is it an inverse correlation or a positive one?  —Preceding unsigned comment added by 68.149.184.246 (talk) 12:18, 31 October 2009 (UTC)
thread_title:  sleep duration line makes no sense 

message: There is a merge suggestion on this page.  It reads "It has been suggested that this article or section be merged into Sleep patterns#Sleep in non-humans. (Discuss) Proposed since June 2012."  The "Discuss" isn't clickable, so I'll discuss here.
I think both articles are long enough as it is, and the division is logical.

message: I learnt that shrews have extremely little sleep, in the order of minutes rather than hours. Is this right? Shouldn't the article mention that? Steinbach (talk) 13:10, 26 March 2017 (UTC)
thread_title:  Shrews 

message: The article says a jellyfish "is the most primitive organism in which sleep-like states have been observed." The image next to it says a nematode "is the most primitive organism in which sleep-like states have been observed." Which of these is more "primitive."  — Preceding unsigned comment added by Ambroginogiusti (talk • contribs) 18:49, 17 July 2018 (UTC)
replies: text: If we translate "more primitive" as "evolutionarily more distant from vertebrates", then jellyfish are more primitive, as they are not bilaterians. If we are asking which species is more complex, I think that would be difficult. (The discovery of sleep in jellyfish is quite recent, by the way.) Looie496 (talk) 20:24, 17 July 2018 (UTC)
thread_title:  Article-Image Disagreement 

message: "If sleep were not essential, one would expect to find:
Animal species that do not sleep at all
Animals that do not need recovery sleep after staying awake longer than usual
Animals that suffer no serious consequences as a result of lack of sleep'
Outside of a few basal animals that have no brain or a very simple one, no animals have been found to date that satisfy any of these criteria "
The paper cited to claim that no animals have been found to satisfy these criteria is outdated. A more recent paper  found no evidence for a sleep rebound mechanism in the freshwater snail Lymnaea stagnalis. 2601:880:C000:55E0:0:0:0:8C2D (talk) 15:51, 6 August 2022 (UTC)
replies: text: Also, pelagic fishes like tuna that are active swimmers their whole life, doesn't seem to sleep either. Rhynchosaur (talk) 15:51, 15 August 2022 (UTC)
thread_title:  Animals without sleep rebound mechanisms do exist 

message: I counted 24 or 25 images of sleeping animals in the article, in addition to pictures of an insect and a nematode. About three images of sleeping animals should be more than enough. Rhynchosaur (talk) 15:51, 15 August 2022 (UTC)
replies: text: Pictures help improve readability, and there aren't so many in this article that they start to impede readability, so I don't see why this is a problem. 204.58.180.206 (talk) 22:34, 19 May 2024 (UTC)
thread_title: Way too many pictures

message: There's this phrase in the invertebrates section, "Decade after decade results mounted that insects do sleep," which I just cannot parse. Is there supposed to be an "of" in between decade and results? Mounted also seems like an unclear and unusual word choice. 204.58.180.206 (talk) 22:42, 19 May 2024 (UTC)
