Avoiding redundancy in captions (and in section headings)[edit]

To avoid redundancy, we normally do not repeat in captions what is already stated explicitly in section headings or the title of an article. There is no need to say an animal is a vertebrate in a section or gallery all about vertebrates, and the article is better off without such a statement. For this reason, I have cut a recent addition.Chiswick Chap (talk) 08:01, 4 February 2015 (UTC)

Deimatic or aposematic[edit]

I have just been editing the blue-ringed octopus article regarding the flashing of their rings when agitated. Some references state that the rings are visible even when the octopus is not being provoked. Should this be included in the "Deimatic or aposematic" section?

Do we know? They could be alluring, or just for contact with other happy octopuses ... Chiswick Chap (talk) 18:44, 2 May 2016 (UTC)
From the page on Aposematism: Blue-ringed octopuses are venomous. They spend much of their time hiding in crevices whilst displaying effective camouflage patterns with their dermal chromatophore cells. However, if they are provoked, they quickly change color, becoming bright yellow with each of the 50-60 rings flashing bright iridescent blue within a third of a second. It has been stated this is an aposematic warning display, although it is pointed out that such statements are often made without the hypothesis being tested. It seems it's not just about the rings. Thus stated, however, it is not known (or, at least, it is not clear) whether this behaviour is aposematic or not. Perhaps the case is made a bit more confusing because blue-ringed octopuses are so venomous. If there is an argument for consistency between articles, aposematism should be mentioned, I suppose. At least to state that the relation exists. Which is not the case for deimatic behaviour. Snjón (talk) 19:17, 2 May 2016 (UTC)
I get the feeling, with no evidence whatsoever, that the rings remain visible because of the translucent skin. They remain visible under normal conditions "by accident". DrChrissy (talk) 19:21, 2 May 2016 (UTC)
Better not mention them here, then. Chiswick Chap (talk) 19:23, 2 May 2016 (UTC)
