Tigers 🐅 🐯

  This is also why hunting vests are bright orange. Easy for humans to spot, and deer get confused by there being a fucking tiger loose in New England.

    Apparently pink works as well, if a hunter wants a second color vest

      That works on the same principle, except the deer thinks you’re a panther.

  Do tigers themselves see themselves as orange, or are they genuinely surprised when humans easily spot them hiding in the grass?

  • Tar_alcaran@sh.itjust.works ⁨4⁩ ⁨days⁩ ago

    My cats are surprised both by me seeing them sitting on an empty floor, and by other cats who they didn’t see sitting on the floor.

    So I can only conclude the answer is semi-perpetual amazement.

    They do not, like almost all mammals they are dichromatic! It’s mostly us and some primates that can see in three wavelengths. Although interestingly enough, fish and birds can see in four wavelengths. Makes me wonder if that contributed to smaller cats being mostly gray and black, to just reduce as much light as possible?

  The green image of the tiger is terrifying. You wouldn’t see it until it’s eyes or teeth were baring down on you in a lush green forest. Thankfully humans weren’t it’s main prey and therefore it likely evolved to appear orange instead…

    You need to explain to them that we’re not prey, but they haven’t figured it out yet.

  So was it just random that their fur is orange and not green? As both would help hunt prey just as well. Or is the advantage of being orange, that it wards away other tigers and predators that might otherwise muscle into its territory and create conflict.

  source

  • Reddfugee42@lemmy.world ⁨4⁩ ⁨days⁩ ago

    Recall that evolution isn’t intelligent. Random mutations do random shit until one is accidentally successful. Random orange that appears green falls right into that scheme 😅

• chonglibloodsport@lemmy.world ⁨4⁩ ⁨days⁩ ago

  Tigers are generally crepuscular which means they’re most active around dawn or dusk, when the sun is very low in the sky. Their orange fur does not stand out so well when everything looks orange under the golden light of dawn.

  Wouldn't a mutation in the deer sight to see orange be vastly evolutionary beneficial?

  source

  • superniceperson@sh.itjust.works ⁨3⁩ ⁨days⁩ ago

    Only in areas with tigers, and then it would only express itself enough if there were enough evolutionary pressure exclusively on that survival tactic.

    As long as other causes of death happen to deer in tiger territories and as long as speed remains a good survival strategy, minor mutations that would only provide an advantage in extreme specific scenarios like a tiger stalking them wouldn’t have a chance to be spread.

    There’s also a whole host of additional brain power that needs to be dedicated to more complex colour blending and processing, and that may add enough delay to offset any potential gain in recognizing a threat.

    Presumably yes, but its still down to a roll of the dice whether a mutation like that happens in the first place, and whether the individuals who have that mutation live long enough to breed, and whether that mutation actually gets passed down, etc

    source
  • Xatolos@reddthat.com ⁨3⁩ ⁨days⁩ ago

    It could, but it might also lead to something harmful for the deer at the same time. I’m not sure if the gene affecting the deer’s eyesight is known, but it could be a pleiotropic gene (a gene that influences multiple traits at once).

    If that’s the case, and the other effect is negative and somehow spreads through the population, it could become a future issue for the deer. Think about humans—we lost the ability to produce our own vitamin C. Almost every other mammal can produce their own (except for hamsters). When this happened, it didn’t harm us right away, so it spread through the population. But over time, it led to issues that weren’t a problem before, like scurvy.

    Same could happen to the deer.

    It’s been far more important, evolution wise, to be agile and quick enough to avoid predators. Like a security camera can only tell you how someone was murdered.

  Is that why cats can be so ginger and still good hunters? My orange stands out so much in the garden, but maybe to dichromatic mice he’s super stealthy?

  source

  • Lyrl@lemm.ee ⁨3⁩ ⁨days⁩ ago

    Elsewhere in the thread, someone said non-primate mammals (like mice) are dichromic (can’t see orange), but birds are quadchromic (see even more colors than trichromics like primates). Is your cat only a good mouse-hunter, and comparatively a bad bird-hunter?

    source

    • Acamon@lemmy.world ⁨3⁩ ⁨days⁩ ago

      He is! 95% mice, very occasional birds. I had attributed that to birds other advantages (mostly being able to harass him by flying at him but not low enough he can reach) but perhaps it’s also the colour!

  this sounds dumb. if that was the reason then why arent they just green so that theyre camoflaged to EVERY animal and not just those with bad eyes

  source

  • Tar_alcaran@sh.itjust.works ⁨4⁩ ⁨days⁩ ago

    Mammals don’t come in green. We have 2 colours available to us, in different amounts: eumelanin, which is dark brown to black, and pheomelanin, which is yellow/red. We can mix those up in any way, or none (for white), but it’ll never be green.

    Now, many other animals don’t have green either, peacock feathers for example, have brown pigment, but they have a structure that makes it look green and blue from wave interference.

    Unfortunately, you can’t really do that with fur, since you need to look at fur from all directions, not just the front.

    So, mammals don’t get green fur.

  • JPAKx4@lemmy.blahaj.zone ⁨4⁩ ⁨days⁩ ago

    Evolution is throwing things against the wall and seeing what sticks (by sticking I mean reproducing bc you have better traits). If every single one of their prey and predators have this color blindness then orange and green would have the same effectiveness and whichever trait comes out first. If a prey/predator evolved to have better color vision then it would quickly become a disadvantage and after millions of years it’s possible they evolve to have green fur.

    There could be other benefits like being easier to attract mates.

    Also some animals can see infrared, so even if their fur was perfect for the environment they could still have issues being spotted, in which case the color doesn’t matter as much and the colors for mating becomes more important.

    • HelixDab2@lemm.ee ⁨4⁩ ⁨days⁩ ago

      Related to this - all fabrics used by the military need to be both Berry-amendment compliant, and NIR compliant. What that means is that, first, they need to be made in the USA (because you don’t want to outsource military equipment if you end up going to war with the country that makes shit for you), and second, it needs to not show up like a sore thumb under infrared light, A lot of fabrics and dyes will show up as hot spots under IR, which means that they show up great with night vision. NIR-compliant fabrics will still appear camouflaged under IR.

      That’s why those nylon-cotton blend Crytek combat pants are something like $450, when the Chinese knock-offs made in poly-cotton are about $70.

      I’ve also heard green coloring is hard to achieve for mammals, but iirc the source was some tumblr post so take that with a grain of salt.

    A) Evolution is not directed. If a pre-tiger happens to be a more advantageous colour, it will have more offspring. There is no goal.

    B) An orange tiger has the same camouflage from its prey’s point of view as a green one, which is the thing that really matters. There is only one species a tiger is afraid of, and it’s humans. I would wager that the orange also happens to act as a signal colour, both to other tigers and other predators (such as humans). Less run-ins and less territorial dispute sound pretty good.

  • NewOldGuard@hexbear.net ⁨4⁩ ⁨days⁩ ago

    Because evolution isn’t an intelligent or designed process, it’s largely random changes where the things that work lead to better survival rates. So it doesn’t matter that animals with more types of cone cells can see them easily, the adaptation was favorable for prey stalking so those are the only group of animals whose sight affected the tigers survivability.

    AFAIK green is more expensive to produce. Plants use it since it’s good at absorbing sunlight, but what’s the advantage to a tiger, if their prey can’t tell the difference?
