Sharks breathing

Surely sharks don't breathe, they don't have lungs. -- Preceding unsigned comment added by (talk) 01:52, 18 May 2020 (UTC)

Sharks do breathe. They just don't inhale oxygen. Breathing refers to the respiration act of inhalation of water through the mouth and exhalation through the gills. -- Preceding unsigned comment added by 2601:46:C780:3FF0:2408:94F9:21C3:FB47 (talk) 14:02, 28 May 2020 (UTC)

As I have always understood the method in which sharks breath, though, is that they actually cannot breathe in the same manner that bony ray-finned fishes do. Those fish have 'gill flaps' that open and close, and facilitate the flow of water through the gills. sharks, however, have only 'gill slits' that do not open and close, and in order to breathe they must remain in forward motion in the water, so water can passively flow through their gills.

Added section 'As a scientific tool'

I have added a section on tonic immobility as a scientific tool. There are many papers on this, so I restricted my coverage. Unfortunately, this entire page is now a little clumsy with several interpretations and descriptions. I have added one of several verifiable sources regarding sharks and tonic immobility, however, I feel using sharks as the lead example of this behaviour is rather imbalanced. I'm prepared to make the changes to redress the balance, however, I do not wish to cause offence or be accused of vandalism. Does anyone have any comments?DrChrissy (talk) 13:34, 3 October 2011 (UTC)

Tickling Trout

Does "tickling trout" have anything to do with this subject? Poachers claim to be able to catch fish this way.

It has been said that a useful means of calming an angry hornet is to catch it in one's mouth, then close the lips. The hornet, believing it to be night, will immediately fall asleep, though this may be a vicious lie.

Like anybody in their right mind is ever gonna try it!
Haha, it's easy enough (and much safer) to test it by simply trapping a hornet in a tight box, which should have the same effect as trapping it in your mouth, and see if it falls asleep. Doesn't seem like it would work though.--M m hawk 01:35, 26 November 2006 (UTC)

Playing Dead

I wanted to research the subject of "Playing Dead", but there was only an article on a band called Play Dead. After searching a while I found this article, and also one on Playing possum. Seems they should be merged, and there should be a disambiguation link from the band's article. Metaeducation 18:43, 5 February 2007 (UTC)

Cannot merge

Tonic isnt playing dead, playing dead is a defense voluntary action, tonic is a chemical nervous thingie.--HalaTruth(?) 13:23, 28 February 2007 (UTC)

I agree, they seem like different mechanisms with the same result. --Sean 19:29, 3 May 2007 (UTC)
I agree as well, I'm watching shark week right now on TV, and it's completely different. Playing dead is a mostly voluntary act performed by the animal, whereas tonic immobility is something the scientists perform on another animal. Although, it should be noted that the flipping sharks upside down trick only works with the smaller sharks -- medium sharks enter this tonic immobility by being touched on their snouts, and the largest sharks sometimes need to be touched on the sides of their snouts in front of their eyes. These are the facts I've heard and seen from the Discovery Channel scientists, but all of these reactions leads me to believe that tonic immobility in sharks is a completely different thing than with other animal species. Sharks are one of the few animals with advanced electrical sensors for their surrounding environments -- by covering the receptor areas on their head where these sensors are clustered is how it appears to work. Which is why this tonic phenomenon in other animals probably works by exploiting something entirely different in other species' anatomies. Fainting goats, opossums playing dead, rabbits freezing in fear, etc, etc is most likely due to a rush of chemicals, whereas tonic sharks are at a loss for electrical stimulus and become temporarily paralyzed. At first I thought it only worked on sharks when the scuba divers used the chain mail suits (metal gloves over receptors) but it appears to even work with uncovered hands as well.
How would you experimentally distinguish between "voluntary" and "involuntary" acts in non-human animals? Currently the article has a section Tonic immobility and a section Thanatosis, but the text suggests they are synonyms. If they are not, proper distinctive criteria are needed. -- (talk) 01:58, 9 April 2020 (UTC)

Fainting goats

Saw this on Discovery Channel. Does it have a place here? --Zeizmic 16:39, 25 April 2007 (UTC)

Tiger Sharks

Tiger sharks cannot be placed into tonic immobility by placing them upside down. Additionally, you can also put most sharks (tigers excluded) by putting your hand on their snouts. Tiger sharks are a bit different in the sense that instead of putting your hand on their snout, you must use 2 hands, one on each side just in front of the eyes.

This was evidenced by Discovery's Shark Man which aired during the 2007 Shark Week.

Actually, a tiger shark was shown successfully placed into tonic by inversion (turning upside down) during the same program, after the tiger had been hooked and pulled up alongside a boat. It was only when "inversion tonic" was attempted in open water, on a free-swimming tiger shark, that it failed (the shark simply turned back upright and went back to swimming). Mike Rutzen, the man making the attempt, believed that "inversion tonic" failed in that case because the shark was unconstrained and not under duress. "Snout tonic" (placing the hand on the snout) appeared far less disabling than "inversion tonic". The shark becomes largely immobile, docile, and relaxed under "snout tonic", but still seems vaguely aware of its surroundings, unlike the coma-like state "inversion tonic" induces. Some sharks appeared to voluntarily seek out "snout tonic", in one case even pushing another shark out of the way to be the one to receive it, and eschewing food in favor of it. My speculation (which wouldn't belong in this article, I admit) is that this "snout tonic" can be an enjoyable state for sharks, but that the shark must more-or-less voluntarily submit to it for it to last for very long.

Is the link to tonic (physiology) the accurate etymology for the word in this context? I thought it was short for catatonic. -- AvatarMN 09:16, 12 August 2007 (UTC)


"Such actions often prove beneficial in the natural environment but, in the modern world of human intervention, can also be fatal."

It would be good if that last part were to be explained further to the reader. -- (talk) 02:32, 3 March 2011 (UTC)

Only thing I can think of that might be meant is a "deer in the headlights" effect - an animal freezing on a road is just staying in the risk area for much longer. -- (talk) 01:26, 9 September 2012 (UTC)

Humans playing dead

According to this article:

...a six year old girl survived by playing dead during a mass shooting. I doubt a child that young would do that through calculated tactics. Are there any studies suggesting that humans instinctively have this behavior? -- Preceding unsigned comment added by (talk) 01:15, 11 March 2014 (UTC)

Etymology / thanato(p)sis

The article currently states:

The term "thanatopsis" (Greek: thanatos "death" + opsis "a sight, view") may be more correct than "thanatosis" which simply refers to death. The addition of the term "-opsis" lends the meaning that the animal only appears to be dead but is in fact alive.[].

This is a kind of pointless tangent for the article. Thanatopsis already has an understood meaning – a contemplation of death (possibly more as the title of Thanatopsis by Bryant).

I think the editor perhaps means that, analyzed properly, 'thanatosis' is the act of dying or the state of being actually dead. However, life scientists and physiologists particularly have used -osis somewhat loosely for centuries for the physical condition of various things, and it's not a huge leap for 'death state' to be the gist of it, without implying that anything has died.

It just seems somewhat weird and speculative so I removed the section. moogsi(blah) 19:49, 19 March 2017 (UTC)
