From the photo you can see the area isn't large,but the pond is really deep,according to the report,the walrus pull the visitor into the pond and drowned him,the animal keeper tried to save the man,but also drowned in the pond.
You can see a long,narrow path along the pond,in the old visit route,visitors must walked through the path,if they didn't stand steady,they may felt off the path and dropped into the water,and the walrus were there.It is said that the visitor who killed by the walrus died of this.Fortunately,the visit route has been changed since then.
