You have inspired me to look into building a terrarium and keeping some spiders. I had a Green Lynx Hunter outside my backdoor for awhile and he was so nice to watch.&lt;p&gt;Also, I hate to be &amp;quot;that guy&amp;quot; but I found a few grammatical errors towards the end of your post. The first being with &amp;quot;No, not poisonous, but all spiders produced venom...&amp;quot;(produced &amp;gt; produce) and &amp;quot;Their are no jumping spiders that have venom&amp;quot;(Their &amp;gt; There). &amp;#x2F;grammar policing over :P Otherwise awesome article, thanks for the inspiration!</text></comment>
