Yeah, those jumping spiders are so cool - and their personalities vary, even within the same species. Some are shy, some inquisitive etc ... and their behaviours are some of the most "intelligent" of the insect world.
We are lucky enough to have the Portia species here and I have been privileged enough to seem them hunt other spiders - sneaking up on them, circling around etc.
Most spiders creep me out but jumping spiders are great.
