"No one has ever noticed the distinctive green chelicerae."

I beg to differ - it was the first thing I noticed the first time I saw one - right before I started yelling for my dad to throw outside before it landed on my dinner ( I was young). Shortly followed by a phone call to my friend to tell her about the cool green 'fangs' leading to demands for my dad to bring it back inside because we had science the next day and I wanted the teacher to identify it. My dad's response was "leave it where it belongs - outside."
