How long do gray whales have barnacles?
The growing barnacle must molt several times, until after 6 to 10 months the adult barnacle is full grown. When we see baby whales, they have baby barnacles visible within days of being born. Thus if you see a baby whale with no barnacles around the blowhole or V of the tail, that baby is almost certainly less than a week old. I have been studying the lives of Gray Whales since 1994 and in all that time I have only seen one gray whale that did not have any barnacles. That whale was known as JJ, a rescued baby Gray Whale. JJ lived at Sea World in San Diego for one year. JJ probably lost contact with his mother at birth and thus never developed any barnacle clusters. Because he had no barnacles, he also had no gray or white patches of skin. JJ was the only black Gray Whale I have ever seen. Those of you who have traveled with me to Baja to see whales have heard the story of JJ. If you haven’t heard the tale, come along some time and ask to hear this story about one unique whale.
