When I was at Point Defiance Zoo recently, my traveling companion @snowleopard made an interesting observation that I was not aware of. He said most captive walruses have their tusks removed because they get damaged scraping the bottom of the pool. The three females we saw there all had no tusks, but there was apparently a male with tusks (on breeding loan) who was off exhibit that day for veterinary procedures. I also happened to see a thumbnail on the internet of a walrus with tusks at Six Flags Discovery Kingdom. Please use this thread to list all the places that have walruses with tusks in captivity. I am NOT interested in all places with walruses, as there is a very extensive thread on that already: Walrus currently in captivity . I am only interested in those with tusks. (The fact that their tusks are routinely removed in my opinion illustrates a failure in enclosure design).
