@davidho Lol, "Hvaldimir" Hval[ur] = whale; Icelandic pronunciation = KVAL-[ihr], so it's easy to see how that corresponds with the west Germanic root "whal" which became "whale" in English.
@davidho were you on the boat? How did this come about? Playing catch with each other, dropping it and the beluga happened to turn up and return it? Or did you spot the beluga and someone thought "let's see if if plays fetch"? Loved watching this anyway, but interested in the #BehaviouralEcology of it 😁
