There are only one type of these but they come in many colors. Any other jumping spider is not from this family. Pretty much only one spider that jumps can kill and it lives on my favorite food... Black Widows' bite don't even hurt some people.
They jump to the walls when you get close as spiders ig have a great sense of vibrations and get away from them immediately. You can see what's up if you tread carefully after they stick to the walls or go chill in a corner! You can do what they did in the video!
Dang that thing is tiny! You’re going to give him a heart before he gets to grow up, lol! I wish I had a good camera like this. I have 3 wild caught pet jumping spiders and I’d love to see their adorable faces. The most I can see is the shine off their eyes if they catch the right lighting. I’m pretty sure they’re all male jumping spiders except one is quite a bit bigger and chunkier so I e wondered if it’s either just more mature or a female.
