BTW, the ONE family of arachnids I like are the Salticidae. The Jumping Spiders. Their venom is NON-human active. And they don't like to bite things way bigger than they are. The Phidippus Audax (Bold Jumper) may be the sole exception to that biting rule. Those ones are the biggest and have a bad attitude to go with it. Meanwhile, if they are relaxed, having a nice day, they will slowly approach you and sometimes even get on your arm to play in the hair. Like a jungle gym, to them, I think.
ALL Jumping Spiders have the same type of eye arrangement. Two big ones facing front, those are focusable by moving their retina. Their vision is excellent, and they have greater acuity and color ranges than we can even dream of. They are active hunters, do not spin a web and sit in it waiting for prey to get caught. They DO anchor a safety line before every jump. They also weave a hide for molting, and females often lay eggs in one. Pretty smart little animals too. Remember, the Jumper FAMILY are human safe. They are the only ones with that eye/face arrangement too. The tiny eyes on the sides/top are for detecting light/shadow changes.
