The difference one year can make!

The difference one year can make!

AP10 is a young adult male southern Alaska resident killer whale that is still rapidly growing. These two photos were taken almost exactly one year apart: The first photo is from 7/11/17 and the second is from 7/10/18. You can see that his dorsal fin has grown a little taller, a little straighter, and a little wider at the base. Additionally, he has picked up two new nicks in his fin which appeared to be relatively fresh when I took his 2018 photo. We don’t always know where these nicks and tears come from; it’s possible some are from conspecifics, and it’s also possible that they may come from interactions with the environment around them. 

It will be interesting to see how AP10 looks in 2019.
