This place is relatively small, but full of wonder.  My favorite creatures today were the two free range turtles.  One was “running” laps around the gift shop and the other one was having his way with the kids birthday area.  They were both pretty large and not at all shy when it came to bumping you out of their way if you were caught in their path.  The San Antonio Aquarium also had a Mermaid, Dinosaurs, Lorikeets, Seahorses, Manta Rays, a Pacific Octopus, Jellyfish, and plenty of other cool stuff.  It is a great place to spend an afternoon.
