Group name

I always thought it was kinda odd that collectively they are "hammerhead sharks", yet none of them have the word "shark" in their name. --70.18.1.227 15:08, 21 April 2007 (UTC)[reply]

Old Comments on Image

I can't see the shark in the picture. Get a new one please. Righteous Monkey 06:15, 17 Apr 2005 (UTC)

Agreed. The shark is too small in the picture. Please get a new image similar to those used in other shark articles. --TheAznSensation 00:21, 11 Jun 2005 (UTC)

WPShark is trying to find a suitable public domain image, it is on the to do list. So a better picture should appear soon! Lenny 06:58, 11 August 2006 (UTC)[reply]

I really like all the photos added and the chart of the 9 different types of hammerheads!Oliviadufr (talk) 02:43, 13 November 2023 (UTC)[reply]

Ampullae of Lorenzini

In the second paragraph of the "Physical Description" section this article states that the Ampullae of Lorenzini are involved in echolocation. Surely this is wrong? They are electric sense organs, and a quick Google check doesn't associate them with echolocation. —Preceding unsigned comment added by 131.111.230.93 (talk • contribs)

Yes that looks like a mistake, I removed it, thanks for spotting it!! --Stefan ^talk 11:38, 11 June 2008 (UTC)[reply]

Inconsistency

Both the family Sphyrnidae and one of the genera, Sphyrna, redirect here, but the other genus, Eusphyra, does not redirect here. This is a slight inconsistency; one genus in a family should not redirect to the family article while the other does not - and genus articles should not direct UP to the family, instead family article should direct DOWN to the genus article. I would propose making this article one of three things: 1) this would be an article about the family with separate articles for both genera (however, since Eusphyra has only one species, it will redirect DOWN to the species); or, 2) this would be an article about the genus Sphyrna and a new article is created for the family; or, 3) this article would be about the informal group of sharks known as hammerheads and new articles are created about the family and genus. Thoughts? Rgrds. --Tombstone (talk) 06:57, 29 January 2009 (UTC)[reply]

Personally, I'd like to see each taxon get its own article. Abyssal (talk) 15:28, 29 January 2009 (UTC)[reply]

Well, the current trend seems to be that if there is only one extant species in a genus, then the genus redirects to the species; I don't have any references in front of me so I don't know if Eusphyra has any extinct species or not -- if so then it would justify having its own article. I would lean towards making this the family article for Sphyrnidae, but I wanted to see if there was any interest in making this an article on the informal grouping called "hammerhead sharks" (similar to how Rabbit is not about any taxonomic group, just the informal group) -- but IMO there isn't enough to really separate out since all but maybe 3-4 aren't commonly called hammerheads. Therefore, I would propose a slight tweaking of this article to lean towards the whole family, and either delete the redirect at Sphyrna in order to redlink it or just create a genus stub there. Rgrds. --Tombstone (talk) 16:37, 29 January 2009 (UTC)[reply]

The German page has some nice maps of the distribution of the different species. I'd like to see that on the English page.John85710 (talk) 22:33, 7 January 2012 (UTC)[reply]

What do they eat?

I came to the article to find out what hammerhead sharks eat, but the article doesn't say, apart from vague references to 'prey'. Surely what any species eats is a fundamental aspect of its biology, which ought to be covered in a Wiki article. It could also be relevant to the problem of their head shape.86.178.84.217 (talk) 17:59, 3 February 2010 (UTC)[reply]

Done Added the section for you. --The High Fin Sperm Whale 18:15, 3 February 2010 (UTC)[reply]

Hammerhead sharks are carnivorous and they eat stingrays and smaller fish and sometimes even plants. However, the Great Hammerhead is the most dangerous of all the hammerhead types because the Great Hammerhead will strike at many things that move. They are very aggressive and they will usually eat squid, lobster, crab, stingray, and even other hammerhead sharks. This is the only hammerhead that divers "studiously" avoid. The head of the hammerhead shark is made for them to be able to see almost everything that is around them. According to a "Your Source of Knowledge" article titled "The Great Hammerhead," the hammerhead shark does not have the ability to see you when coming straight at you due to the shape of it's head; it must turn in order to see you.Tommytrojan14 (talk) 20:47, 15 March 2011 (UTC)TOmmy Tommytrojan14 (talk) 20:41, 15 March 2011 (UTC)Tommy[reply]

Waffling

There's far too much waffling in the article about the role of the cephalofoil. The lede makes it sound like little is known, but several functions are suspected. The next section contradicts this, then misquotes the BBC reference to say a recent study has decided the fact. It would be nice to have a single, definitive statement about what is known and what is guessed. Thanks! 98.210.208.107 (talk) 09:45, 2 March 2011 (UTC)[reply]

Religious Importance

Does anyone know the source of information for this: "The hammerhead shark, also known as mano kihikihi, is not considered a man-eater or niuhi; it is considered to be one of the most respected sharks of the ocean, an aumakua... The hammerhead shark is thought to be the birth animal of some children. "

The reference for this section, 28, "Shark highly respected in Hawaiian culture;" does not make any reference to hammerheads.

In Hawaii; the aumakua concept has been primarily applied to tiger sharks. markdd8. Markdd8 (talk) 18:41, 15 October 2019 (UTC)[reply]

How rare are hammerhead sharks in the waters of Hawai'i?

I am a Native Hawaiian from the island if Maui and as a child, my grandfather always told me that there are times where Hammerhead Sharks will pass through the waters and when that time comes, it's the most beautiful thing I will ever see. I was able to witness this once at a very young age, but then I moved to California and I was wondering if there is a consistent cycle for these sharks to come through to the Hawaiian waters or not. I understand that they are more likely to be in warmer waters, since Hawaiian waters are always warm, shouldn't these sharks be in the Hawaiian waters all the time?

Eye location

I believe the hammerhead's eyes work independently, so they wouldn't have "binocular vision" as I understand it. Thoralor (talk) 11:18, 21 May 2012 (UTC)[reply]

How could you be sure that the shark does not have vision , and better depth perception, in the straight ahead area, due to binocular vision ? Sure they can move their eyes independently, cross eyed style in a human, and get near 360 degree vision from that, but thats not to say they can't get them to work in unison for improved vision forwards. — Preceding unsigned comment added by 101.190.68.66 (talk) 07:50, 19 June 2016 (UTC)[reply]

Couardi and lewini

The article on these species say that they were synonymized some years ago, why do they have separate entries in the table listing the various species?

71.83.153.74 (talk) 00:38, 17 September 2015 (UTC)[reply]

The table was created drawing upon ITIS data, and IUCN Red List status information. ITIS data can be found here: http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=160499 --Danimations (talk) 00:49, 17 September 2015 (UTC)[reply]

Wording of first sentence under Description

The sentence reads "The unknown species range from ..." Can someone provide a clarification on what "unknown species" refers to? Bawb131 (talk) 03:29, 30 November 2015 (UTC)[reply]

Mogadishu shark image.

Should the image of the man with the dead hammerhead be moved to the "Relationship with humans" section or replaced? It seems like an overly unusual situation for the section it's currently in, which is meant to give a physical description. Maybe a picture of a hammerhead in a natural situation would be more suited to its role. Rowsdower1 (talk) 18:22, 19 February 2019 (UTC)[reply]

I am curious about the justification for using a version of the image in which not merely light and color levels, but content, has been changed. This is a striking and beautiful photo in its original version. Why is it appropriate and necessary in an encyclopedia to use an altered version from which street litter and buildings have been photoshopped out? I acknowledge that the small changes in this example don't do obvious and immediate harm, but it seems like a horrible precedent to permit this sort of alteration. Does it make anyone besides me anxious and queasy? --Lex (talk) 18:22, 20 October 2019 (UTC)[reply]

Hello, if you compare the two pictures (original and edited), they are not that different. Street litter and buildings have not been removed ;) I chose to put the edited version because it seemed to have better colors.
