As much as I think these animals should not be held in captivity, seeing Beluga whales in Valencia years ago left a deep impression on me.
They have a large underwater window where you can try to interact with them if it isn’t too crowded. Maybe I was more impressionable back then, but these animals are incredibly smart, almost an alien experience.
The historical Nazi Germany was actually quite supportive of zionist efforts and interestingly the reverse was also true for some time before the holocaust got into full swing.
