Desperately need me a community just for tiger facts like this and pictures of tigers. Greatest of the Big Cats

[–] Hikermick@lemmy.world 10 points 6 days ago (2 children)

Thank you for subscribing to Big Cat Facts

Oh hell yeah. Big Cats are the best

Feel free to open !bigcats or !tiger I'll be your first follower.

I wish lol. I don't have enough time to manage a community though. if someone else made one though i'd follow it instantly

[–] pseudo@jlai.lu 2 points 3 days ago

I vaguely remember someone mentioning a community to give your community ideas to who may want to implement it... I forgot the name.

Do the tigers know they are orange?

[–] TankovayaDiviziya@lemmy.world 21 points 6 days ago (1 children)

Do humans know tigers are green?

Ist is possible to make the own pattern visible? Like with special Cameras and Light?

[–] TheLoneMinon@lemm.ee 1 points 5 days ago

I mean I saw these on people last time I took acid. Does that count?

No, they too are dichromats

[–] Toes@ani.social 10 points 6 days ago

Almost like our eyes evolved to give danger its own colour.

[–] Churbleyimyam@lemm.ee 9 points 6 days ago (1 children)

This must be utterly terrifying for them.

"Why? I've always been orange." - tigers

[–] REDACTED@infosec.pub 8 points 6 days ago (2 children)

Would not green be the obvious route then?

[–] FooBarrington@lemmy.world 15 points 6 days ago

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?

[–] callyral@pawb.social 1 points 5 days ago

idk they could make green but then in, let's say, UV it's like a completely different color, so it'd just be the same situation but in another level

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.

[–] dryfter@lemm.ee 4 points 6 days ago

Ok this makes complete sense now, thank you!

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.

[–] Catoblepas@lemmy.blahaj.zone 187 points 1 week ago (10 children)

It’s also orange because mammals can’t produce green pigments, so orange is the next best thing if your prey is red-green colorblind.

[–] InverseParallax@lemmy.world 103 points 1 week ago* (last edited 1 week ago) (5 children)

Our primary outer protein is basically keratin, which can be tinted orange(carotene), beige (collagen) or brown/black (melanin).

The green pigment is a byproduct of bilirubin catabolism, which we don't have because we use a different pathway to metabolize and recycle it.
