You sneaky scientist you ,how can i possibly hate critters with such BIG eyes .

That’s just the jumping spiders though, which are the cutest among the arachnids, and then with a subtle sleigh of hands you’ve even left out half a dozen eyes from the pics.
And do they really have pupils, or are those just reflections from the cameras that photographed them?

Yes. Consider these comments peer review.

Duckbilled Platypus, I think those are pseudo-pupils, which can also be seen in insects such as dragonflies and praying mantises. The pseudo-pupils appear because the facets of the compound eye which directly face you absorb light and thus look dark, but the facets which aren’t directly facing you reflect light.

@erie Oh cool, yes that seems very plausible. Thank you for answering!

@erie and @duckbiled platypus, not in this case, those ocelli are not compound eyes. I’m pretty sure no arachnid has compound eyes. The ‘pupils’ are just camera reflections.

Yep, yep, yep, yep, yep….
Using a ring flash which surrounds the lens probably has a lot to do with the effect.

Thanks @Adam Yates & @machintelligence, so very likely camera reflection after all. And, I learned about ring flash.

Darn you, I’m not going to get that tune out of my head for the rest of the day!
yep, yep, yep, yep yep
The spider who lives behind my main screen just swung around on a strand of silk to see what I was laughing at. They also started giggling, spraying out lots of silk, reminiscent of Far Side cartoon, https://i2.wp.com/brettfish.co.za/wp-content/uploads/2017/06/spider.jpg
