Lovely photos, i wonder if this is the same specimen I saw as a pup some 30 years ago?
I remember it well as one of them had become stuck between the side of the pool and the glass surround , I reported it but was told not to worry it would free itself. However much later as I was leaving the site I saw the staff trying desperately to push the walrus back into the pool. at least they have shading up now.
I still think about the incident all these years later.
