On Wednesday, August 15, from 1:30 to 2 p.m. CST, Shedd's online audiences will have the chance to ask our shark experts their shark-related questions during our live Twitter chat.

Join the conversation on Twitter (our handle is @shedd_aquarium) using #sharkchat. If you don't have a Twitter account, we're always happy to answer your questions on Facebook, too. Leave us a message or post on our Facebook wall and we'll pass your questions along to our experts.
