Reproductive Organs

I will be focusing on making edits on introduction paragraph of the reproductive organs section in this article. My main goal is to elaborate more on sex determination and sex differentiation (spermatogenesis and oogenesis) to create a better flow between the introduction and the following sections (testes and ovaries). I will also be adding pictures of a bowfin that I have taken into the article that portrays the anus and the urogenital opening. Other than those main edits, I have added more hyperlinks for the introduction paragraph to help the reader understand the concepts. Please let me know if you have any feedback!

Fish skin and scales

Hi!. I would like to propose a revision to the Skin and Scales section. I plan to reorganize, correct and elaborate some details regarding these sections and provide images for reference. Please have a look at my draft. https://en.wikipedia.org/wiki/User:My_Unique_Deoxyribonucleic_Acid/Fish_anatomy My Unique Deoxyribonucleic Acid (talk) 16:52, 29 April 2022 (UTC)[reply]


fish brain

Would anyone happen to have info on fish brain? I came here to look for whether fish can feel pain or not (someone said they can't because they're missing that part of the brain). Now I don't want to write the section myself, as I obviously don't know anything about fish brains... --HJV 15:58, 16 March 2006 (UTC)[reply]

Readers note that we have a specialised article Pain in fish now, created in September 2009. --Florian Blaschke (talk) 13:39, 27 October 2011 (UTC)[reply]

Fish - Anatomy

Fish have very good eyesight and can see in all directions at the same time

Fish have airbag which help to stay upright

Fish that use eyesight for hunting may have good eyesight. Many fish have laterally placed eyes (on the side of their head)so they can see predators approaching. However, some fish have eyes located more dorsally (towards the top of their head). This allows them to see more in front of them. These fish may have grooves in front of their eyes, this lets them see over their nose. So for fish with dorsal eye placement and eye grooves, they have a wide viewing range. The airbag you mention is called a swim bladder. It is a sac of air that the fish can inflate or deflate depending on if they want to go up or down in the water or respond to pressure changesRanled 03:29, 20 November 2006 (UTC).[reply]

Please update the article accordingly, there are many curious people around. `'mikka 18:46, 3 April 2007 (UTC)[reply]

Fin Use

Could someone add for what each fin is used?

It varies from species to species. For example, most species use the caudal fin for propulsion, but
livebearers use their anal fins to impregnate females. Some fishes, such as knifefishes of the family Notopteridae, don't even have a caudal fin. --Ginkgo100 19:10, 26 May 2006 (UTC)[reply

Also Please note that your article needs some info about the skelital structure. If you could provide that soon that would be helpful!

Merger proposed (Pterygiophore)

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

The result was: Merge as proposed. --B. Wolterding (talk) 13:39, 6 December 2007 (UTC)[reply]

I propose to merge the content of

notability
of that article has been questioned. Actually the article has remained a very short stub, and the information could easily be included here.

Please add your comments below. Proposed as part of the

Notability wikiproject. --B. Wolterding 14:42, 1 December 2007 (UTC)[reply

Merger proposed (Lepidotrichia)

I propose to merge the content of

Lepidotrichia into the Spines and rays section of this article. The Lepidotrichia ‎article was started four years ago, and remains only four sentences in length. DiverDave (talk) 05:16, 22 March 2010 (UTC)[reply
]

The merger of
Lepidotrichia into this article has resulted in the automatic addition of a number of inappropriate interwiki links. I've removed the interwiki links to articles treating Lepidotrichia, and I think those relating to fish bones (another redirect) should be removed, as well, as they are misleading. --Florian Blaschke (talk) 13:34, 27 October 2011 (UTC)[reply

Damn, the bot has added them again. --Florian Blaschke (talk) 14:13, 27 October 2011 (UTC)[reply]

Fish reproduction section awful

As of the time I'm writing this, the brief section on reproduction is terrible. It describes a rare, somewhat penis-like fin configuration used by a few types of fish, but says nothing about the reproductive methods used by most fish. For that matter, although I know there's a separate page about cloaca (which are not just a fish structure), there are ought to be more information about fish cloaca. This page in general seems to be about structural parts (fins etc.) and not much else.

"fat fin" not the most common name

I believe the term "fat fin" is not the correct name when referring to the small bit of flesh which protrudes like a tiny fin between the caudal fin and dorsal fins. It isn't present in all fish, but it is present in salmon and trout for certain, not sure about others. and the correct name is Adipose fin.

Doesn't the word "adipose" mean fatty in the first place? Abyssal (talk) 02:59, 28 November 2010 (UTC)[reply]

Opening paragraph

I'm no expert so I won't edit the page directly but I would suggest that the sentence "It can be contrasted with fish physiology, which..." We are not a dictionary. It would be better to put a reference in the See also section. Less is more — Preceding unsigned comment added by 77.59.147.246 (talk) 14:04, 30 December 2013 (UTC)[reply]

Perhaps it's a bit remedial, but I think it's well written and is a decent enough opening. Nothing wrong with clarifying the terminology, and the opener is making the point that the two areas if study are distinct but related. From WP is not a dictionary: “Encyclopedia articles should begin with a good definition and description of one topic (or a few largely or completely synonymous or otherwise highly related topics), but the article should provide other types of information about that topic as well. An encyclopedic definition is more concerned with encyclopedic knowledge (facts) rather than linguistic concerns.” --Agyle (talk) 21:35, 30 December 2013 (UTC)[reply]

Heart

There seems to be some confusion has 2 or 4 chambers - — Preceding unsigned comment added by 77.59.147.246 (talk) 16:48, 30 December 2013 (UTC)[reply]

Yes. There are very many reliable sources on both sides of the issue. The anatomy is well understood, it's just a question of what's consider a “chamber.” I changed the section to explain the different viewpoints. I did not find a reliable source explicitly addressing the confusion, so just cited sources for both (and for a 3-chambered heart). --Agyle (talk) 09:47, 31 December 2013 (UTC)[reply]

Good model article

This article seems to be a well written comprehensive work that is adapted to the encyclopedia style. It is informative, gives broad, general information with lots of direction on where to look if folk are interested in going further with the subject. I think it is a job well done. Thanks. — Preceding unsigned comment added by 70.76.232.129 (talk) 11:14, 22 February 2019 (UTC)[reply]
