What? No Inverts at the Baltimore Aquarium, Rach?
They have shield shrimp in their australian exhibit, look like itty bitty horseshoe crabs.
Its a great place, I will see if any of the other pictures are good enough to share. There was zero crowd (as it was a Friday during the school year) and the weather was perfect for walking around the inner harbor. We have a family membership, it only takes a couple hours to go through the aquarium. My kids all have their favorite parts so its a nice thing to do on a day when they don't have school.
