Talk:Ampullae of Lorenzini/Archive 1

Shark week and magnets

On Discovery's Shark Week ("Shark Feeding Frenzy"), they attempted to confuse the Ampullae of Lorenzini of a hammerhead shark with a powerful magnet, unsuccessfully. Is this something that belongs in the article? Valley2city 06:00, 1 August 2007 (UTC)

Hi sorry if this doesn't conform at all to wiki format. Just wanted to pose this question in case no ones ever thought of it before. Dolphins seem to protect humans when a shark's around according to the shark and dolphin wiki entries. The shark wiki states that 'no sharks will attack a human when a dolphin is around.' I'd like to raise the question of 'could it be because the dolphin somehow disrupts the sharks ability to detect electricity due to having biosonar?'

Need references + problematic statement

The "Electro-magnetic field sensing ability" section especially needs references for each of the statements made.

This statement is clearly problematic -- plants for example (and jellyfish, etc) don't have muscles:

"Since all living creatures produce an electrical field in muscle contractions"

Lorenzini

Who is Lorenzini? Shouldn't there be a page about him or her?RSido (talk) 04:15, 1 February 2009 (UTC)

Maybe, not sure, at least I added that he first described the Ampullae of Lorenzini, please create the page Stephan Lorenzini --Stefan ^talk 14:08, 1 July 2009 (UTC)

"sixth" sense is myth

in the beginning of the article:

"They provide fish with a sixth sense capable of detecting electromagnetic fields as well as temperature gradients."

Implies that humans and other creatures only have five senses. But on another wikipedia page, about well known myths, it says that five senses is a myth, as there are actually many more — Preceding unsigned comment added by Darkkelf99 (talk • contribs) 06:43, 25 July 2011 (UTC)

Electromagnetic field sensing?

No evidence for direct magnetic field sensing. Nor for electrical field itself, only for electric potential. True, the structure can detect magnetic fields because any motion of a conductor will induce an electric field. The term seems to be used because it sounds more general and sexy, possibly getting confused with electromagnetic waves- where in fact it would be the correct term. Also, no source for currents "moved by the magnetic field", rewriten.66.19.92.187 (talk) 07:15, 16 February 2016 (UTC)

Anatomy topic

The ampullae of Lorenzini are anatomical structures, so the article is primarily on an anatomical topic; clearly it makes sense to cover the organ's physiology at least briefly. However, the structure and functioning of the bodies of fish that happen to have ampullae on their snouts is definitely off-topic, as is the overall topic of electroreception. I'll have a go at removing what doesn't belong here, and may attempt a full rewrite, let's see. Chiswick Chap (talk) 12:47, 4 May 2022 (UTC)
