I love killer whales and many many years ago I saw one called Gudrun at the Dolfinarium Harderwijk the only place in The Netherlands that has a tank big enough to house them.

That may soon change though, I live in Rotterdam and the Rotterdam zoo has been rapidly expanding in the last few years. They have added a huge expansion called the "Oceanium" with huge aquariums that mimic specific parts of the ocian from all over the world.
We even got several american sea otters, such wonderfull creatures!.

There has been talk of adding a dolfin tank too, so who knows we may also get some killer whales too!.

I love Rotterdam zoo :)
