A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

Ever notice mammals never seem to come in green? (lemmy.ca)

Birds, fish, reptiles, amphibians, insects? Sure. But no mammals.

So I had to google it. Apparently, there is a sloth that moves around so slowly moss grows all over it and it doesn't care. So it may appear green, but only in the sense that it wears it.

I don't know how relevant this is but I heard human eyes are very good at picking shades of green out. Maybe mammals are generally good at spotting greens and so hiding as a green thing doesn't work as well. Just a guess though

From what other posters are saying, it may be the other way around? That is, most mammals cannot see green, so it doesn't matter from a camouflage perspective among mammals. Humans (and primates in general) are an outlier in this repect.

Bird of prey can, though, so there's that.

I thought veritasium explained in his night vision video that this wasn't the case? I'm not sure though.

I thought Veritasium was a Harry Potter spell but apparently I should have already known and watched a YouTube video before posting my silly thoughts.
