I visited the Pittsburgh Zoo and Aquarium recently and took a picture of their GPO. He (or she...) had some toys in its aquarium and a bat star (Patira miniata. Kind of sleepy while I was there, but otherwise looked in good health. He/she was not very big (well, for a GPO).

i love the squeeky shark!!!!

GPOs in many public aquariums are given toys to play with - some are given plastic dog toys. It's nice to see.
