Great shot, especially considering how hard it is to get a shot of it. During my last couple visits, it wasn't on exhibit.
Thanks for the compliment! It took me a really long time to get my phone's camera to focus on this little guy.
No. The Toronto Zoo is divided into zoogeographic regions so invertebrates are spread out around the zoo. The black widow spider is in the Americas pavilion along with most of the zoo's invertebrate collection.
