This YouTube video of a jumping spider and a mirror shows several things: inter-male aggression, lack of self-recognition (no surprise in this species, but see Wikipedia‘s article on the mirror test for seeing which species have individuals that self-recognize), and, especially, the species’ keen eyesight. The video’s caption identifies the beast:
An adult male of the jumping spider (Carrhotus xanthogramma, family Salticidae) showing combat displays against his own reflection on the mirror again and again. Mid-May 2009 in Japan.

I’ve seen displays like that with a bodybuilder in front of a mirror. I always thought they had self-recognition.
That’s debatable.
Very nice.
You can never have too many jumping spider videos.
I just wish the titmouse that lives outside my office could recognize itself, instead of flying into the window over and over and over and over…
Same here with a sparrow.

It looks like a certain points the spider goes round the back of the mirror to see if he can find his imaginary opponent.
Yep, & jumps back when it isn’t there.
Well, the mirror being moved might have played a role in the jumping back part.
I love jumping spiders. Although I have a question. It seems that he realizes something is wrong at the end…kind of…wait a minute!!?… Am I right?
Cheers! ;D
Seems like some sort of change in behavior.
