[edit] Domestication of Cats
The article strays from the NPOV policy when it mentions that cats are not tame. This is blatantly false, and such rumours are known to be spread by a Cabal of dog lovers. Cats have co-existed happily with humans for thousands of years now. If you really think house cats are not tame, I ask you: would you rather spend time with a cuddly kitten or with a feral cat?
Im not sure about whether this differs from what the article meant but while scubadiving once I saw five LARGE cuttlefish swimming in a V formation. As I moved closer four moved off and disappeared, and one remained allowing me to move closer until I was within a distance of about 30 - 60 centimetres from it. We swam along together for about 30-40 seconds and came around a large rock where the other four were apparently waiting for the one I was swimming with!! The fifth cuttlefish rejoined the formation in its original place and swam off! Most amazing experience I have ever had and I still dont quite fully understand it. Probably never will. But swimming beside it so close, looking in that huge black eye, it just seemed like there was something I wasnt understanding. Anyway, thats my story....
[edit] Plurals of Octopus and Aquarium
I, being a bit of a Latin geek, prefer that the plural of "octopus" be "octopi" and the plural of "aquarium" be "aquaria" and both are standard plurals of these two words; I am asking why the 20:01, 12 December 2005 edits by 71.99.230.82 were removed. Bobryuu 03:39, 13 December 2005 (UTC)
- We do not make changes based upon individual preferences. The correct plural is "octopuses"; "octopi" is simply incorrect. See octopus. "Aquaria" may or may not be technically correct, but common usage is aquariums. - UtherSRG (talk) 11:47, 13 December 2005 (UTC)
- Octopus is not Latin! So why do you want to apply Latin rules to it? --DelftUser 18:27, 13 December 2005 (UTC)
- Thanks for the clarification. I was just wondering Bobryuu 18:35, 13 December 2005 (UTC)
[edit] "Colorblindness" and cuttlefish eyes
If cuttlefish are colourblind how do they blend their colours with the surrounds during camouflage? Also why are cuttlefish claimed to have the best eyes ever? Is it just the polaroid thing? Cause quite a few different animals can do that. The bellman 13:09, 2 February 2006 (UTC)
- I too was wondering at the statement "they cannot see color". If this is true, it needs expanding to explain the apparent anomaly. --Wetman 06:20, 24 May 2006 (UTC)
[edit] cuttlefish husbandry
Hi, In reference to...
- Domestic cuttlefish are very reminiscent of domestic cats, even exhibiting cat-like habits such as resting, pouncing on moving prey, begging owners for food, and even begging for more food than they need or is healthy for them. Like cats, cuttlefish are not truly tame, but rather tolerate and cooperate with their owners to live a comfortable life. But unlike cats, cuttlefish will try to eat other cuttlefish.#
This is my first post on Wikipedia and since some of my articles are already linked to through these pages I thought I should help out and offer any points I can with regards to the captive husbandry of cephalopods.
The analogy which states that cuttlefish are comparable to cats in their captive husbandry is truly bizarre. Having kept both cats and cuttlefish I can see that the references made to their similarities could be applied to almost any predatory animal. Their differences in habit and husbandry are oceans apart :)
- 2 Like octopuses, cuttlefish have been successfully raised as pets in home aquariums, though even their bare necessities are significant. In particular, cuttlefish need a minimum amount of sea water in proportion to their body size, their tank needs to be cleaned every time they ink, they cannot tolerate abrupt changes in light levels, and they cannot coexist with other animals, and rarely ever with other cuttlefish. All other animals of comparable or smaller size, including other cuttlefish, are instinctively seen as food.#
That particular paragraph has several inaccurate statements...
Their tank does not need to be cleaned every time they 'ink'. One of the most important items in a cephalopod aquarium is a protein skimmer (foam fractionator) and that should be of a suitable size to remove the ink from the water within a few hours and perhaps a partial water change of 25% would assist. Also, good quality activated carbon in a filter will assist in its removal.
They can 'happily' co-exist with other animals, in fact I have kept cuttlefish with probably more than 30 species. You just cannot add anything to the aquarium which is part of their natural diet.
As long as the tank is of a suitable size they can easily coexist with other cuttlefish.
Unfamiliar items are often seen as food regardless of its size. A 5cm cuttlefish will tackle a 10cm item of food.
'they cannot tolerate abrupt changes in light levels'. Well, it may startle them for a few seconds but they can tolerate it quite easily, not an accurate statement. They prefer dim lighting compared to the very brights lights of a standard reef aquarium.
Any objections if i spend some time and submit a section on captive husbandry?

- You don't need to ask if you want to edit articles. The whole point of wikipedia is that everybody works on the articles. If you see something you know isn't right go ahead and change it. But make sure to have references to back you up if it's disputed.
- I agree that the parts about cuttlefish as pets could use some work. Calibas 02:43, 24 May 2006 (UTC)
[edit] Colour blindness?
Just a quick question. If cuttlefish can not see colour, 'Although they cannot see color', how can they change their skin colour to match the background? I am very puzzled... —The preceding unsigned comment was added by 86.17.165.90 (talk • contribs) .
- Actually, this was already asked further up on this talk page and there was no real answer to this... hopefully someone else can help. I don't have any idea how they do it, to be honest. Diliff | (Talk) (Contribs) 09:53, 24 May 2006 (UTC)
Indeed. Many thanks, maybe I should get my eyes checked, not the cuttlefish. —The preceding unsigned comment was added by 86.17.165.90 (talk • contribs) .
- As far as I know, it is true that cuttlefish (and all other cephalopods) are colorblind. I don't know the mechanics of how they are otherwise able to blend their color so well, but their eyes have only light brightness sensing cells and no color discriminating cells. - UtherSRG (talk) 10:56, 24 May 2006 (UTC)

- The answer is that they don't match color. They change their colors according to the light and dark tones of the background they mimic, but the hues and saturation often do not match. But if other animals also cannot see hues or saturation either, then this is an effective camouflage. - Gilgamesh 11:52, 28 June 2006 (UTC)
[edit] Question Raised
When I first read the lead in to this article, my question was what is the difference between squid and cuttlefish. I had always equated one with the other. Is there a way to answer this question in the article Felch 13:05, 24 May 2006 (UTC)felch dumas
- Well, the cuttlebone is one of the major differences. Squid just don't have these. And most importantly, cuttlefish are much cuter, necessitating special taxonomic recognition. -- Coelacan | talk 19:13, 24 May 2006 (UTC)
The picture named "Food cuttlefish" with pointy ends seems more like squid than cuttlefish. The east Asian snack food is more likely dried squid (as seen in the picture in squid). 17:29, 08 September 2006 (UTC) —The preceding unsigned comment was added by 192.216.148.139 (talk • contribs) .
[edit] Brains/Intelligence
I'm not qualified to provide this information, but isn't it the case that cuttlefish have fairly large and developed brains? I was hoping to get some information about what is known regarding their supposed intelligence. Thanks. --Davidp 02:32, 27 June 2006 (UTC)
I second that - the octopus article has a quite long section, and I had heard cuttlefish were smart, but no mention here. Someone who knows something want to step up to the plate? 66.194.72.10 08:29, 26 November 2006 (UTC)
[edit] Removed from article
Unsourced, badly written (no offence), rather lacking in a point. The text refers to the ink cuttlefish use to hide themselves.
- Some religious Jews believe the ink is the dye the Torah refers to when it commands Jews to tie strings (tzitzit) to four cornered garments with a string dyed the color "t'cheilet". Some dispute this and claim that either the cuttlefish is not the source of the dye, and others go further saying that we should not try to figure out how to get the dye until the coming of the Moshiach

[edit] Culinary
The dish was written as Risotto Negro, I changed it to Nero. Negro is Spanish, Nero is Italian. Also, they make pasta con il nero di seppia which is a black pasta using cuttlefish ink in the recipe; it might not be necesary to add this in so I'll leave it up to you guys to add it if you want.ABart26 03:08, 26 July 2006 (UTC)
