Etymology relevant to orange colouration in animals

Origin of word 'orange' in English, according to Harper D, Online Etymology Dictionary (https://en.wikipedia.org/wiki/Online_Etymology_Dictionary):

through Old French 'orenge', Italian 'arancia', and Medieval Latin 'orenge'

alternatively/in parallel, from Arabic 'naranj', via Persian 'narang' (meaning an orange tree), and Sanskrit 'naranga-s' (also meaning an orange tree), derived from a proto-Davidian root

Relevant words in Latin:

Noun: orange = arancium (plural -cii)

orange drink = aranciata (plural - ae)

orange tree = aurantium (plural -ii)

orange-coloured = aurantiacus/um/a

gold (noun and adjective) = aurum (plural -i)

gold coin = aureus (plural -ei)

golden-coloured = aureus/um/a

Examples of 'aurantiacus/um/a' in scientific names:

Anthreptes aurantium

Ocular displays in macaques (Macaca), part 2: Japanese macaque (Macaca fuscata) and Sulawesi macaques (Macaca spp.)

...continued from https://www.inaturalist.org/journal/milewski/98203-ocular-displays-in-macaques-macaca-part-1-semets-small-scale-patterns-of-conspicuous-colouration-about-the-eyes-in-the-southern-pig-tailed-macaque-macaca-nemestrina#

https://en.wikipedia.org/wiki/Japanese_macaque

https://en.wikipedia.org/wiki/Celebes_crested_macaque

The main ocular display in Macaca fuscata, as in M. nemestrina, is one that accentuates the stare (https://www.alamy.com/japanese-macaque-snow-monkey-close-up-of-face-nagano-japan-image3327912.html). The relevant colouration is the darkness of the sclera immediately adjacent to the iris, which emboldens the whole eye (https://commons.wikimedia.org/wiki/File:Wildlife_primate_monkey-of-japan_macaca-fuscata_closeup_31-05-2010.jpg and https://www.dreamstime.com/stock-images-face-japanese-macaque-macaca-fuscata-image32246044).

In M. fuscata, an ocular display is weakly-developed, and possibly absent in adults. The eyelids are pale, particularly in juveniles. The sclera, adjacent to the iris, is certainly dark-pigmented, so that in normal views the pale sclera is negligibly visible. This is so particularly because the pterygium (https://www.youtube.com/watch?v=eud5AurOxm0) can be large and darkish, narrowing the visible part of the sclera.

However, in both juveniles and adults, there is in fact a vivid display of the white sclera when the animal glances sideways (https://depositphotos.com/photo/japanese-macaque-face-160912740.html and https://www.flickr.com/photos/serad/4363718078/ and https://depositphotos.com/photo/japanese-macaque-face-160912742.html). This applies to glancing looks to either the left or the right.

Such sideways glances are infrequent. However, the display may be significant. It is as if a 'shifty look' is accentuated, in the ocular colouration of M. fuscata, by a white flash of the sclera that is all the more obvious for being offset by the dark band between the white part of the sclera and the iris itself.

The iris of M. fuscata, like the facial bare skin, is

  • of intermediate tone (neither pale nor dark), and
  • individually variable in tone.

Sundry points about the biogeography and life-history strategies of primates

Primates in the Americas are remarkably small-bodied (https://en.wikipedia.org/wiki/New_World_monkey).

There are no gummivorous (https://en.wikipedia.org/wiki/Gummivore) primates in Asia.

Primates in Madagascar (https://en.wikipedia.org/wiki/List_of_mammals_of_Madagascar) tend to be solitary rather than gregarious.

Of the primates with irregular activity, all but one species live in Madagascar (https://www.inaturalist.org/posts/98222-sundry-points-about-the-biogeography-and-life-history-strategies-of-primates#activity_comment_891fab46-f9fd-477d-bcdc-df22efebcadc).

Only Asia has strictly animal-eating primates (https://www.perplexity.ai/search/which-primates-eat-only-animal-Ld3FqEDFQhSuZPVXIceKlw).

There are no strictly greens-eating primates in the Americas (https://www.perplexity.ai/search/which-primates-eat-only-animal-Ld3FqEDFQhSuZPVXIceKlw).

Colobines (https://en.wikipedia.org/wiki/Colobinae) grow rapidly compared to non leaf-eating monkeys

Callitrichids (https://en.wikipedia.org/wiki/Callitrichidae) grow rapidly compared to other monkeys

Lorises (https://en.wikipedia.org/wiki/Lorisidae) have slow growth and long gestation for strepsirrhines (https://en.wikipedia.org/wiki/Strepsirrhini)

Cheirogaleids (https://en.wikipedia.org/wiki/Cheirogaleidae) have short gestation periods and rapid growth compared to lemurs (https://en.wikipedia.org/wiki/Lemuridae)

Strepsirrhines (https://en.wikipedia.org/wiki/Strepsirrhini) have small neonates and large litters compared to haplorrhines (https://en.wikipedia.org/wiki/Haplorhini)

Ocular displays in macaques (Macaca), part 1: semets (small-scale patterns of conspicuous colouration about the eyes) in the southern pig-tailed macaque (Macaca nemestrina)

@paradoxornithidae @tonyrebelo @jeremygilmore @beartracker @matthewinabinett

Also see https://www.inaturalist.org/posts/54893-ocular-displays-and-what-we-should-call-them-part-2#

Macaca nemestrina (https://en.wikipedia.org/wiki/Southern_pig-tailed_macaque) differs from other cercopithecid monkeys in having eyes with conspicuous colouration.

Furthermore, the pattern of colouration varies greatly within this species, based on age and sex.

In females (https://www.gettyimages.dk/detail/photo/female-southern-pig-tailed-macaque-royalty-free-image/572636219?adppopup=true) and juveniles, the eye is somewhat similar to that in Homo sapiens (https://www.shutterstock.com/video/clip-1018659601-southern-pig-tailed-macaque-macaca-nemestrina-portrait).

The sclera (https://en.wikipedia.org/wiki/Sclera) is unpigmented, and is exposed by the wide configuration of the eyelids (albeit not as wide as in the human species).

Please see https://www.simiansociety.org/nonhuman-primate-species/pigtail-macaque/.

This 'white' sclera is most conspicuous when the animal glances sideways (https://www.istockphoto.com/photo/sad-macaque-macaca-nemestrina-gm508666008-85394433?searchscope=image%2Cfilm and https://www.facebook.com/photo/?fbid=822538356577658&set=pb.100064645033286.-2207520000 and https://www.istockphoto.com/photo/portrait-of-southern-pig-tailed-macaque-macaca-nemestrina-resting-on-a-tree-trunk-gm1418048240-464891924?searchscope=image%2Cfilm and https://www.gettyimages.dk/detail/photo/macaque-wisdom-royalty-free-image/535506761?adppopup=true).

In mature males (https://www.istockphoto.com/photo/male-southern-pig-tailed-macaque-a-medium-sized-old-world-monkey-is-in-natural-gm1016032602-273380979?searchscope=image%2Cfilm and https://www.istockphoto.com/photo/adult-southern-pig-tailed-macaque-or-sunda-pig-tailed-macaque-gm1303623601-395019844?searchscope=image%2Cfilm), a different kind of colouration becomes conspicuous, as follows:

The ocular (https://www.merriam-webster.com/dictionary/ocular) colouration in females and juveniles seems to communicate attention and intention, somewhat as in the human species. That in adult males seems instead simply to emphasise the stare, which is fundamentally antagonistic.

At least in part, the eyes of M. nemestrina are among the most human-like among higher primates (https://www.istockphoto.com/photo/male-pig-tailed-macaque-macaca-nemestrina-eating-an-ananas-fruit-gm2143603643-568707765?searchscope=image%2Cfilm and https://www.istockphoto.com/photo/male-pig-tailed-macaque-macaca-nemestrina-eating-an-ananas-fruit-gm2143602589-568707718?searchscope=image%2Cfilm).
