Have you ever seen how a white whale is fed? You have a chance to see this right now. The white whale which is going to be fed. Each dolphin has its own character. Out of a hundred of caught dolphins 1 or 2 cannot survive in captivity and refuse any food brought to them. If they are not set free they die soon because of stress. Some white whales are trained and prepared for shows in dolphinariums. Petrovich is a bit old for that, it is already 20 (they live for about 30 years), but it is very friendly anyway.
