I've found this little guy yesterday on a trip
I don't know its species, but it belongs to the salticidae family
EDIT: according to iNat, it belongs to the Lyssomanes genus!!
Jumping spiders are very interesting little creatures, their eyesight is amazing !!! They can even move their retina to focus on different spots
You can see it happening in better quality here, its another species but its pretty much the same mechanism
