I remember when I posted my photos from this excellent zoo the Aldabra tortoise indoor exhibit received many curious comments. This photograph shows the edge of the steel bars, and it is cool to actually see the tortoises inside.
I also remembered reading those comment when I saw this exhibit. I noticed it was a little different than your picture portrayed, so I tried to get the edges in the picture. I hope this clears things up for some of the confused people.
